Possible values: - 1 - Do not merge aggregation states from different servers for distributed query processing - in case it is for certain that there are different keys on different shards. - 2 - same as 1 but also apply ORDER BY and LIMIT stages

Previous set of QueryProcessingStage does not allow to do this. But after WithMergeableStateAfterAggregation had been introduced the following queries can be optimized too under optimize_distributed_group_by_sharding_key: - GROUP BY sharding_key LIMIT - GROUP BY sharding_key LIMIT BY - GROUP BY sharding_key ORDER BY And right now it is still not supports: - WITH TOTALS (looks like it can be supported) - WITH ROLLUP (looks like it can be supported) - WITH CUBE - SETTINGS extremes=1 (looks like it can be supported) But will be implemented separatelly. vX: fixes v2: fix WITH * v3: fix extremes v4: fix LIMIT OFFSET (and make a little bit cleaner) v5: fix HAVING v6: fix ORDER BY v7: rebase against 20.7 v8: move out WithMergeableStateAfterAggregation v9: add optimize_distributed_group_by_sharding_key into test names

Process query until the stage where the aggregate functions were calculated and finalized. It will be used for optimize_distributed_group_by_sharding_key. v2: fix aliases v3: Fix protocol ABI breakage due to WithMergeableStateAfterAggregation Conditions >= for QueryProcessingStage::Enum has been verified, and they are ok (in InterpreterSelectQuery).
