MySQL NDB Cluster 7.3 Release Notes
MySQL NDB Cluster 7.3.25 is a new release of NDB Cluster, based on
MySQL Server 5.6 and including features from version 7.3 of the
NDB
storage engine, as well as fixing
a number of recently discovered bugs in previous NDB Cluster
releases.
Obtaining MySQL NDB Cluster 7.3. MySQL NDB Cluster 7.3 source code and binaries can be obtained from https://dev.mysql.com/downloads/cluster/.
For an overview of changes made in MySQL NDB Cluster 7.3, see What is New in NDB Cluster 7.3.
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 5.6 through MySQL 5.6.44 (see Changes in MySQL 5.6.44 (2019-04-25, General Availability)).
Building with CMake3 is now
supported by the
compile-cluster script included
in the NDB
source distribution.
Important Change:
The dependency of ndb_restore on the
NDBT
library, which is used for internal
testing only, has been removed. This means that the program no
longer prints NDBT_ProgramExit: ...
when
terminating. Applications that depend upon this behavior should
be updated to reflect this change when upgrading to this
release.
An NDB
table having both a foreign key on
another NDB
table using ON DELETE
CASCADE
and one or more
TEXT
or
BLOB
columns leaked memory.
As part of this fix, ON DELETE CASCADE
is no
longer supported for foreign keys on NDB
tables when the child table contains a column that uses any of
the BLOB
or TEXT
types.
