I have a function (2.0 written in C#) that has a blob trigger.

 

In this function, whenever a blob is created (to the tune of about 100,000 blobs every 90 minutes) I inspect the blob properties and write some data to a database (SQL Server) table.

 

I am seeing instances where a blob is created, but there is no corresponding row in the table for the blob properties

 

Is it possible that the blobs are being written so quickly that the trigger "misses" and fails to fire?
