Added ADAPTIVE_HASH_INDEX=YES|NO table and index option to InnoDB. The table and index options only have an effect if InnoDB adaptive hash index feature is enabled. - Having the ADAPTIVE_HASH_INDEX TABLE option set to NO will disable adaptive hash index for all indexes in the table that does not have the index option adaptive_hash_index=yes. - Having the ADAPTIVE_HASH_INDEX TABLE option set to YES will enable the adaptive hash index for all indexes in the table that does not have the index option adaptive_hash_index=no. - Using adaptive_hash_index=default deletes the old setting. - One can also use OFF/ON as the options. This is to make it work similar as other existing options. Example: CREATE TABLE t1 (a int primary key, b varchar(100), c int, index (b) adaptive_hash_index=no, index (c)) engine=innodb, adaptive_hash_index=yes; |
