Using sphinxSE in mySQL 5.7 for fulltext search

[lisheng1 zhang1]

We are considering to put sphinxSE into mySQL 5.7 as a storage engine for fulltext search (5.7 innoDB fulltext search works for us feature-wise, we mainly want to explore performance improvement).

I am familiar with mySQL build/deployment basic procedures, here i would like to get guidance at high-level (any big pit-fall so it is not doable or no advantage at all, for example), we expect to join innoDB/myISAM tables with sphinx table, any performance pit-falls?

thanks very much for helps!
