Jihoon Son commented on TAJO-811:
---------------------------------
Hi [~jhkim], thanks for your great contribution!
But, I think that we need to schedule every queries submitted to Tajo including
locally-executed queries and DDLs.
The main application of this feature is the table-level concurrency control to
handle concurrent operation for the same table.
For example, drop table operations for a table should not be executed while any
pre-submitted DML queries for the same table are executed.
So, if you can do easily, do you mind including this feature to the patch?
Otherwise, I'll do at a different issue.
Thanks!
