MySQL Cluster 6.1 - 7.1 Release Notes  /  Changes in MySQL Cluster NDB 7.0  /  Changes in MySQL Cluster NDB 7.0.12 (5.1.41-ndb-7.0.12) (2010-02-03)

Changes in MySQL Cluster NDB 7.0.12 (5.1.41-ndb-7.0.12) (2010-02-03)

Note

MySQL Cluster NDB 7.0.12 was withdrawn shortly after release, due to Bug #51027. Users of the original 7.0.12 release should upgrade to MySQL Cluster NDB 7.0.12b, which fixes this issue (and others). Users of MySQL Cluster NDB 7.0.11 or MySQL Cluster NDB 7.0.11a should upgrade to MySQL Cluster NDB 7.0.11b, if they have not done so already.

This is a testing release only, for the purpose of testing the fix for Bug #49190. This release is otherwise identical to MySQL Cluster NDB 7.0.11b; users of MySQL Cluster NDB 7.0.11 or MySQL Cluster NDB 7.0.11a who are not interested in testing this change should upgrade to MySQL Cluster NDB 7.0.11b (if they have not done so already), then wait until MySQL Cluster NDB 7.0.13 becomes available.

This release also incorporates all bugfixes and changes made in previous MySQL Cluster releases, as well as all bugfixes and feature changes which were added in mainline MySQL 5.1 through MySQL 5.1.41 (see Changes in MySQL 5.1.41 (2009-11-05)).

Note

Functionality Added or Changed

  • Numeric codes used in management server status update messages in the cluster logs have been replaced with text descriptions. (Bug #49627)

    References: See also: Bug #44248.

Bugs Fixed

  • ndbmtd started on a single-core machine could sometimes fail with a Job Buffer Full error when MaxNoOfExecutionThreads was set greater than LockExecuteThreadToCPU. Now a warning is logged when this occurs. (Bug #50582)

  • When a primary key lookup on an NDB table containing one or more BLOB columns was executed in a transaction, a shared lock on any blob tables used by the NDB table was held for the duration of the transaction. (This did not occur for indexed or non-indexed WHERE conditions.)

    Now in such cases, the lock is released after all BLOB data has been read. (Bug #49190)
