Pull request overview
This PR fixes a regression when terminating pending orchestrations that haven't completed their first execution round. The issue occurs for pending suborchestrations or orchestrations started by entities, where no instance entity exists yet in Azure Table Storage. The fix changes the Azure Table operation from MergeEntityAsync (which requires the entity to exist) to InsertOrMergeEntityAsync (which creates the entity if it doesn't exist).
Key Changes:
- Updated
UpdateStatusForTerminationAsyncto useInsertOrMergeEntityAsyncinstead ofMergeEntityAsync - Removed the
ETag.Allparameter which is not needed for insert-or-merge operations - Aligns the termination code with other instance status update patterns used elsewhere in the same file

When terminating a pending orchestration, I call
MergeEntityAsyncbecause I assume the instance entity already exists. This assumption is incorrect in the case that an orchestration has since been purged after the termination message has been enqueued. This PR adds a check to see if the instance entity exists, and if the execution ID matches that of the termination message's, before attempting to update the entity's status to terminated.Solves #1287
