If you have query that gets timed out and you want to adjust the run-time limitation:

Open Azure Data Explorer Web UI à Settings à Connection à Query timeout (in minutes)




Query timeout can be adjusted between 1-60 minutes.




Read Query data in Azure Data Explorer for more information on using the Web UI

Ideally, by following query best practices and making sure the query (and perhaps the underlying schema of the data) are optimized, one should be able to actually decrease the query's runtime, and not consider increasing the default query timeout.
