Philip Dubé	44fa6cc2db	Now compiles for 11 & 12, but 12 crashes on missing symbol we're supposed to get from ruleutils	2019-07-16 21:52:20 +00:00
Murat Tuncer	f20258ef10	Expand count distinct support We can now support more complex count distinct operations by pulling necessary columns to coordinator and evalutating the aggreage at coordinator. It supports broad range of expression with the restriction that the expression must contain a column.	2018-07-06 09:44:20 +03:00
Onder Kalaci	832c91e28c	Move processing each part of the query into its own functions This commit doesn't change any of the logic at all. Instead, the goal is to: * Get rid of any code duplication * Incremental changes to the optimizer made it slightly hard to follow the code, improve that and make it easier to implement new features * Simplify the code by moving each part of query processing (e.g., DISTINCT, LIMIT etc) into its own function * Make the interaction between each part of the query more obvious (e.g., How DISTINCT affects LIMIT etc)	2018-04-27 17:32:38 +03:00
Onder Kalaci	ee748d9140	Unify extendedOpNode Processing Before this commit, we had a divergence among the creation of master/worker extended op nodes. This commit moves the related parts into a single place and allows the creation of master/extended op nodes to share a common data structure.	2018-04-24 11:56:38 +03:00
