[settings]: introduce new query complexity settings for leaf-nodes
 2020-09-18 14:05:10 +03:00

b41421cb1c [settings]: introduce new query complexity settings for leaf-nodes 
The new setting should allow to control query complexity on leaf nodes
excluding the final merging stage on the root-node. For example, distributed
query that reads 1k rows from 5 shards will breach the `max_rows_to_read=5000`,
while effectively every shard reads only 1k rows. With setting `max_rows_to_read_leaf=1500`
this limit won't be reached and query will succeed since every shard reads
not more that ~1k rows.

fffeeeba06 Force WithMergeableStateAfterAggregation via distributed_group_by_no_merge (convert to UInt64) 
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

50a312534c Extend parallel_distributed_insert_select to run INSERT into local table 
Before this patch there was:

- parallel_distributed_insert_select=1, that executes:

    INSERT INTO dist_out SELECT ... FROM underlying_dist_in

After this patch there will be:

- parallel_distributed_insert_select=2, that executes:

    INSERT INTO underlying_dist_out SELECT ... FROM underlying_dist_in

And cover the behaviour w/o integration test, by using the following
techincs:
- SYSTEM STOP DISTRIBUTED SENDS
- prefer_localhost_replica=0

6507247328 optimize_skip_unused_shards=2 will disable it for nested distributed queries 
P.S. Looks like settings can be converted between SettingUInt64 and
SettingBool without breaking binary protocol.

FWIW maybe it is a good idea to change the semantics of the settings as
follow (but I guess that changing semantic is not a good idea, better to
add new settings and deprecate old ones):
- optimize_skip_unused_shards -- accept nesting level on which the
  optimization will work
- force_skip_optimize_shards_nesting -- accept nesting level on which
  the optimization will work

c1cf31f87d Introduce min_insert_block_size_{rows,bytes}_for_materialized_views 
With tons of MATERIALIZED VIEW attached to one table pushing to this
views can be pretty memory consuming due to blocks squashing, add
ability to control this separatelly for MATERIALIZED VIEWs.

Plus squashing is useless if the underlying engine is Buffer().

038235684d Add optimize_distributed_group_by_sharding_key and disable it by default 
I know at least one way to fool that optimization, by using as sharding
key something like `if(col1>0, col1, col2)` (although this is not common
sharding key I would say, but can be useful if this will work
correctly), so let's disable it by default.

After #8756 the problem with 1 thread for each (distributed table, disk)
for distributed sends became even worse (since there can be multiple
disks), so use predefined thread pool for this tasks, that can be
controlled with background_distributed_schedule_pool_size knob.
