brkyvz opened a new pull request #26018: Track active streaming queries in the SparkSession.sharedState
URL: https://github.com/apache/spark/pull/26018
 
 
   ### What changes were proposed in this pull request?
   
   
   This moves the tracking of active queries from a per SparkSession state, to the shared SparkSession for better safety in isolated Spark Session environments.
   
   ### Why are the changes needed?
   
   We have checks to prevent the restarting of the same stream on the same spark session, but we can actually make that better in multi-tenant environments by actually putting that state in the SharedState instead of SessionState. This would allow a more comprehensive check for multi-tenant clusters.
   
   ### Does this PR introduce any user-facing change?
   
   No
   
   ### How was this patch tested?
   
   WIP
