MariaDB

This is a list of MariaDB storage engines that are not distributed with MySQL. I think that most of them will work with MySQL, but not all – at least CassandraSE doesn’t.

EngineDescriptionIntroduced
XtraDBA fully-compatible fork ofInnoDB, mantained by PerconaBig Bang
AriaA crash-sageMyISAM, also used for internal temptablesBig Bang
TokuDBA transactional engine with innovative buffers and high compression, by TokuTek10.0
mroongaSupports fulltext searches with Chinese, Japanese and Korean languages10.0
SPIDERShards tables through multiple servers10.0
OQGRAPHUsed to implement tree structures10.0
SequenceReturns a sequence of numbers as a resultset10.0
CONNECTSupport several external data sources (data files, DBMS’s…)10.0
CassandraSEA bridge to Apache Cassandra10.0
SphinxSEA bridge to Sphinx5.2
FederatedXA richer fork ofFederatedBig Bang

Notes:

  • XtraDB is the default and should be preferred to InnoDB, unless it has a bug which affects you (but XtraDB fixes several InnoDB bugs).
  • OQGRAPH was introduced during the Big Bang or soon after, but disabled in 5.5. Seethis post.
  • FederatedX is called Federated, so it’s possible that you are already using it and you don’t know.
  • CONNECT will hopefully obsoleteCSVand FederatedX, but some features are still missing. For example, CONNECT cannot store NULL values in flat files.
  • With MariaDB you need to specifySQL_MODE='NO_ENGINE_SUBSTITUTION'. If you mistype the engine name, or try to use a disabled engine, you want to get an error, rather than silently switch to XtraDB.

    • Obsolete storage engines:

    PBXT(Big Bang – 5.3) – A transactional engine which aimed to be “somewhere between InnoDB and MyISAM”. Seemed to support foreign keys better than InnoDB (I couldn’t reproduce a tirgger+FK bug and it had more options), but alas it’s dead.

    Enjoy!
