MySQL是否支持BITMAP索引？

Question

MySQL支持BITMAP索引吗？语法是什么？

mysql> CREATE BITMAP INDEX ON tb1(num);
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use near 'BITMA
P INDEX ON tb1(num)' at line 1

Answer 1

简短的回答 - 不,它没有.截至今天(MySQL 8.0),它只包含两种类型的索引 - HASH和BTREE.
