Merge pull request #2866 from citusdata/fix_83_regression 
Do not record relation accessess unnecessarily
 2019-08-08 18:47:58 +02:00
Onder Kalaci 060ac11476 Do not record relation accessess unnecessarily 
Before this commit, we've recorded the relation accesses in 3 different
places
    - FindPlacementListConnection         -- applies all executor in tx block
    - StartPlacementExecutionOnSession()  -- adaptive executor only
    - StartPlacementListConnection()      -- router/real-time only

This is different than Citus 8.2, and could lead to query execution times
increase considerably on multi-shard commands in transaction block
that are on partitioned tables.

Benchmarks:

```
1+8 c5.4xlarge cluster

Empty distributed partitioned table with 365 partitions: https://gist.github.com/onderkalaci/1edace4ed6bd6f061c8a15594865bb51#file-partitions_365-sql

./pgbench -f /tmp/multi_shard.sql -c10 -j10 -P 1 -T 120 postgres://citus:w3r6KLJpv3mxe9E-NIUeJw@c.fy5fkjcv45vcepaogqcaskmmkee.db.citusdata.com:5432/citus?sslmode=require

cat  /tmp/multi_shard.sql
BEGIN;
	DELETE FROM collections_list;
	DELETE FROM collections_list;
	DELETE FROM collections_list;
COMMIT;
cat  /tmp/single_shard.sql
BEGIN;
	DELETE FROM collections_list WHERE key = :aid;
	DELETE FROM collections_list WHERE key = :aid;
	DELETE FROM collections_list WHERE key = :aid;
COMMIT;

cat  /tmp/mix.sql
BEGIN;
	DELETE FROM collections_list WHERE key = :aid;
	DELETE FROM collections_list WHERE key = :aid;
	DELETE FROM collections_list WHERE key = :aid;

	DELETE FROM collections_list;
	DELETE FROM collections_list;
	DELETE FROM collections_list;
COMMIT;
```

The table shows `latency average` of pgbench runs explained above, so we have a pretty solid improvement even over 8.2.2.

becomes obsolete, just remove it.

Onder Kalaci b2e01d0745 Refactor switching to sequential mode 
We don't need to wait until the execution. As soon as we realize
that we need sequential execution, we should do it.
