Functionality Added or Changed
Important Change; Cluster API:
memory page sizes in bytes rather than kilobytes, it has been
page_size_bytes. The name
page_size_kb is now deprecated and thus
subject to removal in a future release, although it currently
remains supported for reasons of backward compatibility. See

A periodic failure to flush the send buffer by the
NDB TCP transporter could cause a
unnecessary delay of 10 ms between operations.
A race condition could occur (very rarely) when the release of a GCI was followed by a data node failure. (Bug #33793)
Some tuple scans caused the wrong memory page to be accessed, leading to invalid results. This issue could affect both in-memory and Disk Data tables. (Bug #33739)
The server failed to reject properly the creation of an
NDB table having an unindexed
The Cluster backup process could not detect when there was no more disk space and instead continued to run until killed manually. Now the backup fails with an appropriate error when disk space is exhausted. (Bug #28647)

Cluster version supporting Micro-GCPs from an older version that
did not support these.
A workaround when restoring to MySQL Cluster releases supporting
micro-GCPs previous to MySQL Cluster NDB 6.3.8 is to perform a
32-bit shift on the
epoch column values to
reduce them to their proper size.
Transactions containing inserts or reads would hang during
made from NDB API applications built against a MySQL Cluster
version that did not support micro-GCPs accessing a later
version that supported micro-GCPs. This issue was observed while
upgrading from MySQL Cluster NDB 6.1.23 to MySQL Cluster NDB
6.2.10 when the API application built against the earlier
version attempted to access a data node already running the
later version, even after disabling micro-GCPs by setting
