I'm looking at the Extended events session AlwaysOn_health.
One of the events is lock_redo_blocked and I'm trying to find the blocker.
First of all, I haven't found any documentation for this event. The only info I've found was in sys.dm_xe_object_columns and mentioned some of the columns.
I'm trying to figure out what does the resource_0 refer to in this picture:
the number is a bigint so it rules out object_id (which is int). I also haven't been able to match it to either partition_id or hobt_id.
Is there any way I can find the blocker after the fact?
I don't have data from sys.dm_exec_requests at that time (as advised here: troubleshoot-availability-group-exceeded-rto)
