When binlog is enabled, trasaction takes a lot of time to do
sync operation on innodb fts table. This leads to block
of other transaction commit. To avoid this failure, remove
the fulltext sync operation during transaction commit. So
reverted MDEV-25581 related patches.
We filed MDEV-31105 to avoid the memory consumption
problem during fulltext sync operation.
Problem:
========
InnoDB FTS requesting the fts sync of the table once the fts
cache size reaches 1/10 of innodb_ft_cache_size. But fts_sync()
releases cache lock when writing the word. By doing this, InnoDB
insert thread increases the innodb fts cache memory and
SYNC operation will take more time to complete.
Solution:
=========
Remove the fts sync operation(FTS_MSG_SYNC_TABLE) from
the fts optimize background thread. Instead of that,
allow user thread to sync the InnoDB fts cache when
the cache size exceeds 512 kb. User thread holds
cache lock while doing cache syncing, it make sure that
other threads doesn't add the docs into the cache.
Removed FTS_MSG_SYNC_TABLE and its related function
because we do remove the FTS_MSG_SYNC_TABLE message
itself.
Removed fts_sync_index_check() and all related
function because other threads doesn't add while
cache operation going on.
InnoDB DDL fails when it tries to sync the table
when innodb_force_recovery is set to 2. Problem
is that fts_optimize_wq is not initialized when
there are no background threads. fts_sync_during_ddl()
should check whether fts_optimize_wq is initialized.
AUTO_INCREMENT values are nondeterministic after crash recovery.
While MDEV-6076 guarantees that the AUTO_INCREMENT values of committed
transactions will not roll back, it is possible that the AUTO_INCREMENT
values will be durably incremented for incomplete transactions. So
changing the test case to avoid showing the result of AUTO_INCREMENT value.
