The Gap Between Applications and Analytics, and "How Lakebase Solves It"
The Problem Nobody Likes to Admit. Imagine this scenario: your data team has built a flawless lakehouse. Ingest pipelines, bronze/silver/gold tiers, gleaming dashboards. Everything is working perfectly. Until someone asks: "And the production app? Where does it store the transactional data?" That's where the headache begins. You need a separate OLTP database (Postgres, MySQL, DynamoDB...), CDC pipelines to bring data into the lakehouse, reverse ETL to return enriched data to the app, and an infrastructure team to keep it all running. The result? Data silos, synchronization latency, operational complexity, and ever-increasing costs. Traditional Architecture (and Its Pain Points) Here's how most companies operate today: Pain points in this architecture: Multiple tools and suppliers for managing Significant latency between writing on OLTP and availability on Lakehouse. Fragmented governance — Unity Catalog doesn't see the external bank. High operational costs associated with synchronization pipelines. What is Lakebase? Lakebase is a fully managed Postgres database natively integrated with the Databricks Data Intelligence Platform. It is designed to bridge the gap between transactional (OLTP) and analytical (OLAP) workloads, unifying everything into a single ecosystem . In simple terms: it's like having a high-performance Postgres server living inside your lakehouse , with unified governance via Unity Catalog, native bidirectional synchronization, and modern capabilities such as autoscaling, scale-to-zero, and database branching. The New Architecture with Lakebase: What changes? Zero external database infrastructure Native bidirectional synchronization (no Debezium, no Airflow, no pain) Unified governance through the Unity Catalog A single control plane for OLTP + OLAP The Architectural Innovations of Lakebase Lakebase is not "just another managed Postgres." It brings modern data engineering concepts to the transactional world. 1. Separation of Compute and Storage Unlike traditional data banks where CPU and disk are coupled, Lakebase completely separates computing resources from storage. This means you scale each independently, paying only for what you use. 2. Copy-on-Write Storage The storage system uses a copy-on-write approach. In practice, when you create a branch of the database, there is no data duplication —only the changes are stored separately. This makes operations like branching and restoring virtually instantaneous. 3. Autoscaling and Scale-to-Zero The compute system automatically adjusts its capacity based on demand. During periods of inactivity, the database scales to zero , eliminating costs. When a request arrives, it "wakes up" in seconds. Database Branching: Git for Your Data This is probably the most innovative feature. Just as developers create branches in Git to work on isolated features, Lakebase allows you to create branches for the entire database . Powerful use cases: Development : each developer has their own branch of the database, without interfering with production. Migration testing : test schema changes in an isolated branch before applying them to production. Instant Restore : Restore the database to any point in time (configurable window from 0 to 30 days) by creating a branch from that point. Two-Way Synchronization: The End of Reverse ETL One of the biggest advantages is the native synchronization between Lakehouse and Lakebase: Synced Tables (Lakehouse → Lakebase) Unity Catalog tables are automatically synchronized to Lakebase, allowing applications to query rich analytical data with low latency. Supports Snapshot, Triggered, and Continuous modes. Lakehouse Sync (Lakebase → Lakehouse) Transactional data from Lakebase is continuously replicated to Delta tables in the Unity Catalog using Change Data Capture (CDC). The destination tables follow the SCD Type 2 standard , maintaining a complete history of changes. This completely eliminates the need for: External CDC tools (Debezium, Fivetran) Reverse ETL pipelines (Census, Hightouch) Custom synchronization jobs in Airflow/Prefect Three Strategic Use Cases Feature Serving for Real-Time ML Lakebase functions as an online store for Databricks' Feature Store. Features computed in the lakehouse are synchronized via Synced Tables to Lakebase, from where ML models query them with millisecond latency. State of AI Agents AI agents need to persist state between requests — conversation context, action history, workflow data. Lakebase provides a native transactional database to store this state with ACID consistency. Transactional Data for Applications Databricks Apps (or any external application) can use Lakebase as their primary database. The integration is native: simply add the Lakebase project as a resource in your app. Additionally, the Data API offers a PostgREST-compatible REST interface for direct HTTP access. Comparison: Before and After Availability Lakebase Autoscaling is available in the following AWS regions: us-east-1, us-east-2,us-west-2 ca-central-1, sa-east-1 eu-central-1, eu-west-1,eu-west-2 ap-south-1, ap-southeast-1,ap-southeast-2 The presence in sa-east-1 is particularly relevant for us in the Brazilian community, ensuring low latency for applications hosted in Brazil. Conclusion Lakebase represents a paradigm shift: instead of treating OLTP and OLAP as separate worlds that need complex "bridges," it unifies them into a single platform. For Brazilian data teams, this means: Fewer tools to manage and integrate. Fewer pipelines that silently break down at 3 a.m. More time focused on generating value with data. Real governance across the entire data lifecycle — from transactional writing to the executive dashboard. Lakehouse finally has its native transactional database. And it speaks Postgres. This post was inspired by concepts from the official Databricks documentation. For more technical details, please refer to the Lakebase documentation .

Unable to load large delta table in azure ml studio
I am writing to report an issue that I am currently experiencing while trying to read a delta table from Azure ML. I have already created data assets to register the delta table, which is located at an ADLS location. However, when attempting to load the data, I have noticed that for large data sizes it is taking an exceedingly long time to load. I have confirmed that for small data sizes, the data is returned within few seconds, which leads me to believe that there may be an issue with the scalability of the data loading process. I would greatly appreciate it if you could investigate this issue and provide me with any recommendations or solutions to resolve this issue. I can provide additional details such as the size of the data, the steps I am taking to load the data, and any error messages if required. I'm following this document: https://learn.microsoft.com/en-us/python/api/mltable/mltable.mltable?view=azure-ml-py#mltable-mltable-from-delta-lake Using this command to read delta table using data asset URI from mltable import from_delta_lake mltable_ts = from_delta_lake(delta_table_uri=<DATA ASSET URI>, timestamp_as_of="2999-08-26T00:00:00Z", include_path_column=True)Train a simple Recommendation Engine using the new Azure AI Studio

Building Multi-Agent Orchestration Using Microsoft Semantic Kernel: A Complete Step-by-Step Guide
What You Will Build By the end of this guide, you will have a working multi-agent system where 4 specialist AI agents collaborate to diagnose production issues: ClientAnalyst — Analyzes browser, JavaScript, CORS, uploads, and UI symptoms NetworkAnalyst — Analyzes DNS, TCP/IP, TLS, load balancers, and firewalls ServerAnalyst — Analyzes backend logs, database, deployments, and resource limits Coordinator — Synthesizes all findings into a root cause report with a prioritized action plan These agents don't just run in sequence — they debate, cross-examine, and challenge each other's findings through a shared conversation, producing a diagnosis that's better than any single agent could achieve alone. Table of Contents Why Multi-Agent? The Problem with Single Agents Architecture Overview Understanding the Key SK Components The Actor Model — How InProcessRuntime Works Setting Up Your Development Environment Step-by-Step: Building the Multi-Agent Analyzer The Agent Interaction Flow — Round by Round Bugs I Found & Fixed — Lessons Learned Running with Different AI Providers What to Build Next 1. Why Multi-Agent? The Problem with Single Agents A single AI agent analyzing a production issue is like having one doctor diagnose everything — they'll catch issues in their specialty but miss cross-domain connections. Consider this problem: "Users report 504 Gateway Timeout errors when uploading files larger than 10MB. Started after Friday's deployment. Worse during peak hours." A single agent might say "it's a server timeout" and stop. But the real root cause often spans multiple layers: The client is sending chunked uploads with an incorrect Content-Length header (client-side bug) The load balancer has a 30-second timeout that's too short for large uploads (network config) The server recently deployed a new request body parser that's 3x slower (server-side regression) The combination only fails during peak hours because connection pool saturation amplifies the latency No single perspective catches this. You need specialists who analyze independently, then debate to find the cross-layer causal chain. That's what multi-agent orchestration gives you. The 5 Orchestration Patterns in SK Semantic Kernel provides 5 built-in patterns for agent collaboration: SEQUENTIAL: A → B → C → Done (pipeline — each builds on previous) CONCURRENT: ↗ A ↘ Task → B → Aggregate ↘ C ↗ (parallel — results merged) GROUP CHAT: A ↔ B ↔ C ↔ D ← We use this one (rounds, shared history, debate) HANDOFF: A → (stuck?) → B → (complex?) → Human (escalation with human-in-the-loop) MAGENTIC: LLM picks who speaks next dynamically (AI-driven speaker selection) We use GroupChatOrchestration with RoundRobinGroupChatManager because our problem requires agents to see each other's work, challenge assumptions, and build on each other's analysis across two rounds. 2. Architecture Overview Here's the complete architecture of what we're building: 3. Understanding the Key SK Components Before we write code, let's understand the 5 components we'll use and the design pattern each implements: ChatCompletionAgent — Strategy Pattern The agent definition. Each agent is a combination of: name — unique identifier (used in round-robin ordering) instructions — the persona and rules (this is the prompt engineering) service — which AI provider to call (Strategy Pattern — swap providers without changing agent logic) description — what other agents/tools understand about this agent agent = ChatCompletionAgent( name="ClientAnalyst", instructions="You are ONLY ClientAnalyst...", service=gemini_service, # ← Strategy: swap to OpenAI with zero changes description="Analyzes client-side issues", ) GroupChatOrchestration — Mediator Pattern The orchestration defines HOW agents interact. It's the Mediator — agents don't talk to each other directly. Instead, the orchestration manages a shared ChatHistory and routes messages through the Manager. RoundRobinGroupChatManager — Strategy Pattern The Manager decides WHO speaks next. RoundRobinGroupChatManager cycles through agents in a fixed order. SK also provides AutomaticGroupChatManager where the LLM decides who speaks next. max_rounds is the total number of messages per agent or cycle. With 4 agents and max_rounds=8, each agent speaks exactly twice. InProcessRuntime — Actor Model Abstraction The execution engine. Every agent becomes an "actor" with its own kind of mailbox (message queue). The runtime delivers messages between actors. Key properties: No shared state — agents communicate only through messages Sequential processing — each agent processes one message at a time Location transparency — same code works in-process today, distributed tomorrow agent_response_callback — Observer Pattern A function that fires after EVERY agent response. We use it to display each agent's output in real-time with emoji labels and round numbers. 4. The Actor Model — How InProcessRuntime Works The Actor Model is a concurrency pattern where each entity is an isolated "actor" with a private mailbox. Here's what happens inside InProcessRuntime when we run our demo: runtime.start() │ ├── Creates internal message loop (asyncio event loop) │ orchestration.invoke(task="504 timeout...", runtime=runtime) │ ├── Creates Actor[Orchestrator] → manages overall flow ├── Creates Actor[Manager] → RoundRobinGroupChatManager ├── Creates Actor[ClientAnalyst] → mailbox created, waiting ├── Creates Actor[NetworkAnalyst] → mailbox created, waiting ├── Creates Actor[ServerAnalyst] → mailbox created, waiting └── Creates Actor[Coordinator] → mailbox created, waiting Manager receives "start" message │ ├── Checks turn order: [Client, Network, Server, Coordinator] ├── Sends task to ClientAnalyst mailbox │ → ClientAnalyst processes: calls LLM → response │ → Response added to shared ChatHistory │ → callback fires (displayed in Notebook UI) │ → Sends "done" back to Manager │ ├── Manager updates: turn_index=1 ├── Sends to NetworkAnalyst mailbox │ → Same flow... │ ├── ... (ServerAnalyst, Coordinator for Round 1) │ ├── Manager checks: messages=4, max_rounds=8 → continue │ ├── Round 2: same cycle with cross-examination │ └── After message 8: Manager sends "complete" → OrchestrationResult resolves → result.get() returns final answer runtime.stop_when_idle() → All mailboxes empty → clean shutdown The Actor Model guarantees: No race conditions (each actor processes one message at a time) No deadlocks (no shared locks to contend for) No shared mutable state (agents communicate only via messages) 5.

ClientAnalyst and NetworkAnalyst both point to body size. Question: Was the deployment a backend-only change or did it include infra?" Round 2: Cross-Examination (Messages 5-8) Msg Agent What They Do 5 ClientAnalyst "I agree with NetworkAnalyst that the load balancer timeout is likely a factor — the 85% freeze point matches the 30-second LB timeout for a 10MB upload on our average upload speed. However, I disagree with ServerAnalyst about thread pool exhaustion because the UI shows a clean 504, not a connection reset." 6 NetworkAnalyst "ServerAnalyst's point about the recent deployment is critical — if the new request parser is 3x slower, that would push uploads past the LB timeout. I can confirm the LB has a 30s idle timeout. The fix is both: increase LB timeout AND optimize the parser." 7 ServerAnalyst "Responding to Coordinator's question: The deployment was backend-only — a new multipart parser using streaming instead of buffered reads. ClientAnalyst is correct that the 504 is from the LB, not the app. The app itself returns 200 after 45 seconds, but the LB kills the connection at 30." 8 Coordinator Produces final structured report with root cause: "The backend deployment introduced a slower multipart parser (45s vs 15s for 10MB). The load balancer's 30s timeout kills the connection at ~85% progress. Fix: immediate — increase LB timeout to 120s. Short-term — optimize parser. Long-term — implement chunked uploads with progress resumption." Notice: The Round 2 analysis is dramatically better than Round 1. Agents reference each other by name, build on each other's findings, and the Coordinator can synthesize a cross-layer causal chain that no single agent could have produced. I made a small adjustment to the issue with Azure Web Apps. Please find the details below from testing carried out using Google Gemini: 8. Bugs I Found & Fixed — Lessons Learned Building this demo taught me several important lessons about multi-agent systems: Bug 1: Agents Speaking Only Once Symptom: Only 4 messages instead of 8. Root cause: The agents list was missing the Coordinator. It was defined in a separate cell and wasn't included in the members list. Fix: All 4 agents must be in the same list passed to GroupChatOrchestration. Bug 2: NetworkAnalyst Says "I'm Ready to Proceed" Symptom: NetworkAnalyst's Round 2 response was just "I'm ready to proceed with the analysis" — no actual content. Root cause: The Coordinator's Round 1 message was assigning tasks ("NetworkAnalyst, please check the load balancer config"), and the agent was acknowledging the assignment instead of analyzing. Fix: Added explicit constraint to Coordinator: "Round 1 MUST NOT assign tasks — observation + questions ONLY." Bug 3: ServerAnalyst Says "As NetworkAnalyst, I..." Symptom: ServerAnalyst's response started with "As NetworkAnalyst, I believe..." Root cause: LLM identity bleeding. When agents share ChatHistory, the LLM sometimes loses track of which agent it's currently playing. This is especially common with Gemini. Fix: Identity anchoring at the very top of every agent's instructions: "You are ONLY ServerAnalyst. You must NEVER speak as ClientAnalyst, NetworkAnalyst, or Coordinator." Bug 4: Gemini Gives Thin/Empty Responses Symptom: Some agents responded with just one sentence or "I concur." Root cause: Gemini 2.5 Flash is more concise than GPT-4o by default. Without explicit length requirements, it takes shortcuts. Fix: Added "Every response MUST be at least 200 words" and "Answer the Coordinator's questions" to every specialist's instructions. Bug 5: Coordinator's Report is 18K Characters Symptom: The Coordinator's Round 2 response was absurdly long — repeating everything every specialist said. Fix: Added word limits: "Round 1 max 300 words, Round 2 max 800 words" and "Synthesize, don't echo." Bug 6: MAX_ROUNDS Math Symptom: With MAX_ROUNDS=9, ClientAnalyst spoke a 3rd time after the Coordinator's final report — breaking the clean 2-round structure. Fix: MAX_ROUNDS must equal (number of agents × number of rounds). For 4 agents × 2 rounds = 8. 9. Running with Different AI Providers The beauty of SK's Strategy Pattern is that you change ONE LINE to switch providers. Everything else — agents, orchestration, callbacks, validation — stays identical. Gemini setup: from semantic_kernel.connectors.ai.google.google_ai import GoogleAIChatCompletion service = GoogleAIChatCompletion( gemini_model_id="gemini-2.5-flash", api_key=os.getenv("GOOGLE_AI_API_KEY"), ) OpenAI Setup from semantic_kernel.connectors.ai.open_ai import OpenAIChatCompletion service = OpenAIChatCompletion( ai_model_id="gpt-4o", api_key=os.getenv("OPEN_AI_API_KEY"), ) 10. What to Build Next Add Plugins to Agents Give agents real tools — not just LLM reasoning - looks exciting right ;) class NetworkDiagnosticPlugin: (description="Pings a host and returns latency") def ping(self, host: str) -> str: result = subprocess.run(["ping", "-c", "3", host], capture_output=True, text=True) return result.stdout class LogSearchPlugin: (description="Searches server logs for error patterns") def search_logs(self, pattern: str, hours: int = 1) -> str: # Query your log aggregator (Splunk, ELK, Azure Monitor) return query_logs(pattern, hours) Add Filters for Governance Intercept every agent call for PII redaction and audit logging: .filter(filter_type=FilterTypes.FUNCTION_INVOCATION) async def audit_filter(context, next): print(f"[AUDIT] {context.function.name} called by agent") await next(context) print(f"[AUDIT] {context.function.name} returned") Try Different Orchestration Patterns Replace GroupChat with Sequential for a pipeline approach: # Instead of debate, each agent builds on the previous orchestration = SequentialOrchestration( members=[client_agent, network_agent, server_agent, coordinator_agent] ) Or Concurrent for parallel analysis: # All specialists analyze simultaneously, Coordinator aggregates orchestration = ConcurrentOrchestration( members=[client_agent, network_agent, server_agent] ) Deploy to Azure Move from InProcessRuntime to Azure Container Apps for production scaling. The agent code doesn't change — only the runtime. Summary The key insight from building this demo: multi-agent systems produce better results than single agents not because each agent is smarter, but because the debate structure forces cross-domain thinking that a single prompt can never achieve. The Coordinator's final report consistently identifies causal chains that span client, network, and server layers — exactly the kind of insight that production incident response teams need. Semantic Kernel makes this possible with clean separation of concerns: agents define WHAT to analyze, orchestration defines HOW they interact, the manager defines WHO speaks when, the runtime handles WHERE it executes, and callbacks let you OBSERVE everything. Each piece is independently swappable — that's the power of SK from Microsoft.

Fine-Tuning Phi-3.5 Model Fine-tuning a language model like Phi-3.5 is a crucial step in adapting it to perform specific tasks or cater to specific domains. This section will walk through what fine-tuning is, its importance in NLP, and how to fine-tune the Phi-3.5 model using Azure Model Catalog for different languages and tasks. We'll also explore a code example and best practices for evaluating and validating the fine-tuned model. What is Fine-Tuning? Fine-tuning refers to the process of taking a pre-trained model and adapting it to a specific task or dataset by training it further on domain-specific data. In the context of NLP, fine-tuning is often required to ensure that the language model understands the nuances of a particular language, industry-specific terminology, or a specific use case. Why Fine-Tuning is Necessary Pre-trained Large Language Models (LLMs) are trained on diverse datasets and can handle various tasks like text summarization, generation, and question answering. However, they may not perform optimally in specialized domains without fine-tuning. The goal of fine-tuning is to enhance the model's performance on specific tasks by leveraging its prior knowledge while adapting it to new contexts. Challenges of Fine-Tuning Resource Intensiveness: Fine-tuning large models can be computationally expensive, requiring significant hardware resources. Storage Costs: Each fine-tuned model can be large, leading to increased storage needs when deploying multiple models for different tasks. LoRA and QLoRA To address these challenges, techniques like LoRA (Low-rank Adaptation) and QLoRA (Quantized Low-rank Adaptation) have emerged. Both methods aim to make the fine-tuning process more efficient: LoRA: This technique reduces the number of trainable parameters by introducing low-rank matrices into the model while keeping the original model weights frozen. This approach minimizes memory usage and speeds up the fine-tuning process. QLoRA: An enhancement of LoRA, QLoRA incorporates quantization techniques to further reduce memory requirements and increase the efficiency of the fine-tuning process. It allows for the deployment of large models on consumer hardware without the extensive resource demands typically associated with full fine-tuning. from transformers import AutoModelForSequenceClassification, Trainer, TrainingArguments from peft import get_peft_model, LoraConfig # Load a pre-trained model model = AutoModelForSequenceClassification.from_pretrained("bert-base-uncased") # Configure LoRA lora_config = LoraConfig( r=16, # Rank lora_alpha=32, lora_dropout=0.1, ) # Wrap the model with LoRA model = get_peft_model(model, lora_config) # Define training arguments training_args = TrainingArguments( output_dir="./results", evaluation_strategy="epoch", learning_rate=2e-5, per_device_train_batch_size=16, per_device_eval_batch_size=16, num_train_epochs=3, ) # Create a Trainer trainer = Trainer( model=model, args=training_args, train_dataset=train_dataset, eval_dataset=eval_dataset, ) # Start fine-tuning trainer.train() This code outlines how to set up a model for fine-tuning using LoRA, which can significantly reduce the resource requirements while still adapting the model effectively to specific tasks. In summary, fine-tuning with methods like LoRA and QLoRA is essential for optimizing pre-trained models for specific applications in NLP, making it feasible to deploy these powerful models in various domains efficiently. Why is Fine-Tuning Important in NLP? Task-Specific Performance: Fine-tuning helps improve performance for tasks like text classification, machine translation, or sentiment analysis in specific domains (e.g., legal, healthcare). Language-Specific Adaptation: Since models like Phi-3.5 are trained on general datasets, fine-tuning helps them handle industry-specific jargon or linguistic quirks. Efficient Resource Utilization: Instead of training a model from scratch, fine-tuning leverages pre-trained knowledge, saving computational resources and time.

Specify the Model: Link the fine-tuned Phi-3.5 model to the deployment pipeline. Deploy the Model: Select the option to deploy the model to the chosen compute resource. Test the Deployment: Once the model is deployed, test the endpoint by sending sample requests to verify the predictions. Configuration Steps (Compute, Resources, Scaling) During deployment, Azure AI Foundry allows you to configure essential aspects like compute type, resource allocation, and scaling options. Compute Type: Choose between CPU or GPU clusters depending on the computational intensity of the model. Resource Allocation: Define the minimum and maximum resources to be allocated for the deployment. For real-time applications, use Azure Kubernetes Service (AKS) for high availability. For batch inference, Azure Container Instances (ACI) is suitable. Auto-Scaling: Set up automatic scaling of the compute instances based on the number of requests. For example, configure the deployment to start with 1 node and scale to 10 nodes during peak usage. Cost Comparison: Phi-3.5 vs. Larger Language Models When comparing the costs of using Phi-3.5 with larger language models (LLMs), several factors come into play, including computational resources, pricing structures, and performance efficiency. Here’s a breakdown: Cost Efficiency Phi-3.5: Designed as a Small Language Model (SLM), Phi-3.5 is optimized for lower computational costs. It offers competitive performance at a fraction of the cost of larger models, making it suitable for budget-conscious projects. The smaller size (3.8 billion parameters) allows for reduced resource consumption during both training and inference. Larger Language Models (e.g., GPT-3.5): Typically require more computational resources, leading to higher operational costs. Larger models may incur additional costs for storage and processing power, especially in cloud environments. Performance vs. Cost Performance Parity: Phi-3.5 has been shown to achieve performance parity with larger models on various benchmarks, including language comprehension and reasoning tasks. This means that for many applications, Phi-3.5 can deliver similar results to larger models without the associated costs. Use Case Suitability: For simpler tasks or applications that do not require extensive factual knowledge, Phi-3.5 is often the more cost-effective choice. Larger models may still be preferred for complex tasks requiring deep contextual understanding or extensive factual recall.
