ROHIT K RAMWAL commented on AIRFLOW-5511:
-----------------------------------------
updated priority as minor as impact is on mssql backend which is not official backend for airflow.
Looks like the the feature in 6e96a59344a4_make_taskinstance_pool_not_nullable.py to bulkupdate the existing rows to pool = defaultpool are breaking as mssql doesnt support such operation. can mssql be handled separately with dropping the ti_pool index , making bulk update and recreating with index.
> MSSQL resetdb /initdb for 1.10.5 fails to create tables
