Changes in MySQL NDB Cluster 7.2.32 (5.5.59-ndb-7.2.32) (2018-01-17, General Availability)

   MySQL NDB Cluster 7.2.32 is a new release of NDB Cluster,
   incorporating new features in the NDB storage engine, and fixing
   recently discovered bugs in previous MySQL NDB Cluster 7.2
   development releases.

   Obtaining MySQL NDB Cluster 7.2.  MySQL NDB Cluster 7.2 source code
   and binaries can be obtained from
   http://dev.mysql.com/downloads/cluster/.

   This release also incorporates all bug fixes and changes made in
   previous NDB Cluster releases, as well as all bug fixes and feature
   changes which were added in mainline MySQL 5.5 through MySQL 5.5.59
   (see Changes in MySQL 5.5.59 (Not yet released, General availability)
   ( http://dev.mysql.com/doc/relnotes/mysql/5.5/en/news-5-5-59.html )).

   Bugs Fixed

     * NDB Replication: On an SQL node not being used for a
       replication channel with sql_log_bin=0 it was possible after
       creating and populating an NDB table for a table map event to be
       written to the binary log for the created table with no
       corresponding row events. This led to problems when this log was
       later used by a slave cluster replicating from the mysqld where
       this table was created.  Fixed this by adding support for
       maintaining a cumulative any_value bitmap for global checkpoint
       event operations that represents bits set consistently for all
       rows of a specific table in a given epoch, and by adding a check
       to determine whether all operations (rows) for a specific table
       are all marked as NOLOGGING, to prevent the addition of this
       table to the Table_map held by the binlog injector.  As part of
       this fix, the NDB API adds a new getNextEventOpInEpoch3() method
       which provides information about any AnyValue received by making
       it possible to retrieve the cumulative any_value bitmap.  (Bug
       #26333981)

     * The NDBFS block's OM_SYNC flag is intended to make sure
       that all FSWRITEREQ signals used for a given file are
       synchronized, but was ignored by platforms that do not support
       O_SYNC, meaning that this feature did not behave properly on
       those platforms. Now the synchronization flag is used on those
       platforms that do not support O_SYNC.  (Bug #76975, Bug
       #21049554)
