Mroonga 14.08 has been released!

Mroonga is a MySQL storage engine that supports fast fulltext search and geolocation search. It is CJK ready. It uses Groonga as a storage and fulltext search engine.

Mroonga 14.08 has been released!

Changes

Here are important changes in this release:

Improvements

  • We use CMake for building instead of the GNU Autotools.

    Using configure is deprecated. We recommend using cmake to build from source.

    Please refer Others about how to build from source with cmake.

Fixes

  • Fixed a bug that SELECT returned wrong result when we used multiple primary keys and primary keys included VARBINARY or BLOB type column.

    This bug only occurred in Mroonga 14.07.

    This bug doesn’t break an index. So, we don’t need to execute REINDEX command after this fix.

    If this bug occurred, the following query retrieved nothing.

    CREATE TABLE logs (
  id INT,
  content VARBINARY(256),
  PRIMARY KEY (id, content)
) ENGINE=Mroonga DEFAULT CHARSET=utf8mb4;

INSERT INTO logs(id, content) VALUES (1, 'aaa');
INSERT INTO logs(id, content) VALUES (2, 'bbb');

SELECT * FROM logs WHERE content = 'aaa';
