Onder Kalaci	5d68a13139	Add order by to multi_shard_update_delete	2019-05-02 20:09:33 +03:00
Onder Kalaci	004f28e18c	Sort output of RETURNING ... The feature is only intended for getting consistent outputs for the regression tests. RETURNING does not have any ordering gurantees and with unified executor, the ordering of query executions on the shards are also becoming unpredictable. Thus, we're enforcing ordering when a GUC is set. We implicitly add an `ORDER BY` something equivalent of ` RETURNING expr1, expr2, .. ,exprN ORDER BY expr1, expr2, .. ,exprN ` As described in the code comments as well, this is probably not the most performant approach we could implement. However, since we're only targeting regression tests, I don't see any issues with that. If we decide to expand this to a feature to users, we should revisit the implementation and improve the performance.	2019-04-24 11:51:19 +03:00
