FULLTEXT indexes not supported on partitioned tables

Production Risk

Medium — DDL rejected.

What this means

MySQL does not support FULLTEXT indexes on partitioned InnoDB or MyISAM tables.

Why it happens
  1. 1Attempting to create a FULLTEXT index on a partitioned table.
  2. 2Attempting to partition a table that already has a FULLTEXT index.
How to reproduce
trigger — this will error
trigger — this will error
ALTER TABLE articles PARTITION BY HASH(id) PARTITIONS 4; -- table has FULLTEXT index

expected output

ERROR 1757 (HY000): FULLTEXT searches are not supported for partitioned tables.

Fix

Remove the FULLTEXT index before partitioning

Remove the FULLTEXT index before partitioning
ALTER TABLE articles DROP INDEX ft_content;
ALTER TABLE articles PARTITION BY HASH(id) PARTITIONS 4;

Why this works

Partitioned tables cannot have FULLTEXT indexes; use an external search engine if both are needed.
