If you want to add to the table and index partitioning, clustering, it is only in the following order:
create table,
1. alter add .... clustering = yes
2. and alter table ... partition to ...
reverse order :
1. alter table ... partition to ...
2. alter add .... clustering = yes
not WORK, rror 1911 (HY000): Unknown option 'clustering'.
EXAMPLE: drop table t1
CREATE TABLE `t1` ( `id_high` bigint(20) unsigned NOT NULL, `id_low` bigint(20) unsigned NOT NULL, `modified` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP -- KEY `clstr_time` (`modified`) `clustering` = yes, -- KEY `clstr_key_id_id` (`id_high`) `clustering` = yes, -- PRIMARY KEY (`modified`,`id_high`) ) ENGINE=TokuDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci
alter table n3.t1 add PRIMARY KEY `t1_pk` (`modified` ASC, `id_high` ASC); alter table t1 add key clstr_key (`id_high`) CLUSTERING=YES;
