http://dev.mysql.com/doc/refman/5.1/en/partitioning-limitations.html这里找到如下这段话:Key caches not supported. Key caches are not supported for partitioned tables. The CACHE INDEX and LOAD INDEX INTO CACHE statements, when you attempt to use them on tables having user-defined partitioning, fail with the errors The storage engine for the table doesn't support assign_to_keycache and The storage engine for the table doesn't support preload_keys, respectively.
什么叫INDEX的索引块?
增大key_buffer_size对分区表来说,到底有没有效果?
