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 5.6.43 (see Changes in MySQL 5.6.43 (2019-01-21, General Availability)).
Asynchronous disconnection of mysqld from the
cluster caused any subsequent attempt to start an NDB API
transaction to fail. If this occurred during a bulk delete
operation, the SQL layer called
HA::end_bulk_delete()
, whose implementation
by ha_ndbcluster
assumed that a transaction
had been started, and could fail if this was not the case. This
problem is fixed by checking that the transaction pointer used
by this method is set before referencing it.
