Changes in MySQL NDB Cluster 7.5.22 (5.7.34-ndb-7.5.22) (2021-04-21, General Availability)
MySQL NDB Cluster 7.5.22 is a new release of MySQL NDB
Cluster 7.5, based on MySQL Server 5.7 and including features
in version 7.5 of the NDB
(https://dev.mysql.com/doc/refman/5.7/en/mysql-cluster.html)
storage engine, as well as fixing recently discovered bugs in
previous NDB Cluster releases.
Obtaining MySQL NDB Cluster 7.5. MySQL NDB Cluster 7.5
source code and binaries can be obtained from
https://dev.mysql.com/downloads/cluster/.
For an overview of changes made in MySQL NDB Cluster 7.5, see
What is New in NDB Cluster 7.5
(https://dev.mysql.com/doc/refman/5.7/en/mysql-cluster-what-is-new-7-5.html).
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 5.7
through MySQL 5.7.33 (see Changes in MySQL 5.7.33
(2021-01-18, General Availability)
(https://dev.mysql.com/doc/relnotes/mysql/5.7/en/news-5-7-33.html)).
Bugs Fixed
* Running out of disk space while performing an NDB backup
could lead to an unplanned shutdown of the cluster. (Bug
#32367250)
* The default number of partitions per node (shown in
ndb_desc output as PartitionCount) is calculated using
the lowest number of LDM threads employed by any single
live node, and was done only once, even after data nodes
left or joined the cluster, possibly with a new
configuration changing the LDM thread count and thus the
default partition count. Now in such cases, we make sure
the default number of partitions per node is recalculated
whenever data nodes join or leave the cluster. (Bug
#32183985)
