What is the best partition technique for large table with TEXT column?
You can't partition an InnoDB table with a fulltext index, which would make intuitive sense, since it's difficult to envision how fulltext searches on (what would presumably be implemented as) multiple underlying fulltext indexes (one for each partition) would be able to give meaningful relevance and query expansion results.

Full-text search (FTS) and foreign keys are not supported by InnoDB partitioned tables. For more information, see Section 12.9.5, “Full-Text Restrictions” and Section 18.6.2, “Partitioning Limitations Relating to Storage Engines”.

The limitation applies to all storage engines.
