Add distributed_directory_monitor_split_batch_on_failure setting (OFF by
default), that will split the batch and send files one by one in case of
retriable errors.
v2: more error codes
This way the remote nodes will not need to send all the rows, so this
will decrease network io and also this will make queries w/
optimize_aggregation_in_order=1/LIMIT X and w/o ORDER BY faster since it
initiator will not need to read all the rows, only first X (but note
that for this you need to your data to be sharded correctly or you may
get inaccurate results).
Note, that having lots of processing stages will increase the complexity
of interpreter (it is already not that clean and simple right now).
Although using separate QueryProcessingStage looks pretty natural.
Another option is to make WithMergeableStateAfterAggregation always, but
in this case you will not be able to disable only this optimization,
i.e. if there will be some issue with it.
v2: fix OFFSET
v3: convert 01814_distributed_push_down_limit test to .sh and add retries
v4: add test with OFFSET
v5: add new query stage into the bash completion
v6/tests: use LIMIT O,L syntax over LIMIT L OFFSET O since it is broken in ANTLR parser

v7/tests: set use_hedged_requests to 0, to avoid excessive log entries on retries

v2: fix optimize_skip_unused_shards_rewrite_in for sharding_key wrapped into function
v3: fix column name for optimize_skip_unused_shards_rewrite_in
v4: fix optimize_skip_unused_shards_rewrite_in with Null
v5:
- squash with Remove query argument for IStreamFactory::createForShard()
- use proper column after function execution (using sharding_key_column_name)
- update the test reference since (X) now is tuple(X)

Only queries slower then the value of this setting will go to system.query_log,
i.e. something like slow_query_log in mysql.
v2: log_queries_min_time renamed to log_queries_min_query_duration_ms
v3: add current_database into system.query_thread_log
v4: rewrite test using current_database
v5: fix query_duration_ms in system.query_thread_log
* for CSV and TSV input formats input_format_csv_enum_as_number,
input_format_tsv_enum_as_number settings should be enabled in order to
treat input value as enum id
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.
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

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

- optimize_skip_unused_shards_nesting (allows control nesting level for
shards skipping optimization)
- force_skip_optimize_shards_nesting (allows control nesting level for
checking was shards skipped or not)
- deprecates force_skip_optimize_shards_no_nested
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

Added a new table engine backed by Apache Kafka,
it allows near real-time ingestion or ETL with
exactly-once semantics.
It doesn’t store any data on disk, so data must
be materialized into a physical table to allow
random access.
Currently it only supports reading, no insertion.
