Peter Vary commented on HIVE-22654:
-----------------------------------
[~rajesh.balamohan]: Any specific reason behind not using
"buildQueryWithINClause" for this case as it is done in most cases in
TxnHandler? (I personally prefer the batched way used in MetastoreDirectSql,
but I really do not like to use different approach for solving the same issue
in the same class)
Thanks,
Peter
