The InnoDB adaptive hash index is sometimes degrading the performance of InnoDB, and it is sometimes disabled to get more consistent performance. We should have a compile-time option to disable the adaptive hash index. Let us introduce two options: OPTION(WITH_INNODB_AHI "Include innodb_adaptive_hash_index" ON) OPTION(WITH_INNODB_ROOT_GUESS "Cache index root block descriptors" ON) where WITH_INNODB_AHI always implies WITH_INNODB_ROOT_GUESS. As part of this change, the misleadingly named function trx_search_latch_release_if_reserved(trx) will be replaced with the macro trx_assert_no_search_latch(trx) that will be empty unless BTR_CUR_HASH_ADAPT is defined (cmake -DWITH_INNODB_AHI=ON). We will also remove the unused column INFORMATION_SCHEMA.INNODB_TRX.TRX_ADAPTIVE_HASH_TIMEOUT. In MariaDB Server 10.1, it used to reflect the value of trx_t::search_latch_timeout which could be adjusted during row_search_for_mysql(). In 10.2, there is no such field. Other than the removal of the unused column TRX_ADAPTIVE_HASH_TIMEOUT, this is an almost non-functional change to the server when using the default build options. Some tests are adjusted so that they will work with both -DWITH_INNODB_AHI=ON and -DWITH_INNODB_AHI=OFF. The test innodb.innodb_monitor has been renamed to innodb.monitor in order to track MySQL 5.7, and the duplicate tests sys_vars.innodb_monitor_* are removed.
