I am writing a web-app for my studies which includes fulltext search and foreign keys.
I have read somewhere, MyISAM engine is suitable for fulltext searching, and InnoDB for foreign keys.
In this situation what engine should I use for the best performance?
Kindly tell me, In this situation what engine I have to use for improve performance?
The performance of each storage engine will depend on the queries you perform. However, be aware that different tables within the same database can use different storage engines.
Why MyISAM engine does not support foreign key relationship and InnoDB does?
As documented under Foreign Key Differences:
At a later stage, foreign key constraints will be implemented for
MyISAM
tables as well.
Therefore, foreign key constraints have simply not yet been implemented in MyISAM
.
EDIT: As that comment is removed from docs, it appears that it is no longer planned to implement foreign key constraints in MyISAM
engine.
Why MyISAM engine does support full text search and InnoDB does not?
As documented under What Is New in MySQL 5.6:
You can create
FULLTEXT
indexes onInnoDB
tables, and query them using theMATCH() ... AGAINST
syntax.
Therefore, full text search has been implemented in InnoDB
as of MySQL 5.6.
