What is New in NDB Cluster still supported in production; for information about NDB Cluster 7.6, see What is New in NDB Cluster 7.6. For similar information about NDB Cluster 7.5, see What is New in NDB Cluster 7.5. NDB Cluster 7.4 and 7.3 are previous GA releases still supported in production, although we recommend that new deployments for production use NDB Cluster 8.0; see MySQL NDB Cluster 7.3 and NDB Cluster 7.4. What is New in NDB Cluster 8.0 Major changes and new features in NDB Cluster 8.0 which are likely to be of interest are shown in the following list: • Compatibility enhancements.   The following changes reduce longstanding nonessential differences in  NDB  behavior as compared to that of other MySQL storage engines: • Development in parallel with MySQL server.   Beginning with this release, MySQL NDB Cluster is being developed in parallel with the standard MySQL 8.0 server under a new unified release model with the following features: •NDB 8.0 is developed in, built from, and released with the MySQL 8.0 source code tree. •The numbering scheme for NDB Cluster 8.0 releases follows the scheme for MySQL 8.0, starting with version 8.0.13. •Building the source with  NDB  support appends  -cluster  to the version string returned by  mysql - V , as shown here: NDB  binaries continue to display both the MySQL Server version and the  NDB  engine version, like this: shell ≫ mysql -V mysql Ver 8.0.26-cluster for Linux on x86_64 (Source distribution) shell>  ndb_mgm -V MySQL distrib mysql-8.0.26 ndb-8.0.26, for Linux (x86_64) In MySQL Cluster NDB 8.0, these two version numbers are always the same. To build the MySQL 8.0.13 (or later) source with NDB Cluster support, use the CMake option  - DWITH_NDBCLUSTER . • Platform support notes.   NDB 8.0 makes the following changes in platform support: • NDBCLUSTER  no longer supports 32-bit platforms. Beginning with NDB 8.0.21, the NDB build process checks the system architecture and aborts if it is not a 64-bit platform. •Beginning with NDB 8.0.18, it is possible to build  NDB  from source for 64-bit  ARM  CPUs. Currently, this support is source-only, and we do not provide any precompiled binaries for this platform. • Database and table names.   As of NDB 8.0.18, the 63-byte limit on identifiers for databases and tables is removed. These identifiers can now use up to 64 bytes, as for such objects using other MySQL storage engines. See Section 23.1.7.11, “Previous NDB Cluster Issues Resolved in NDB Cluster 8.0” . • Generated names for foreign keys.  NDB  (version 8.0.18 and later) now uses the pattern tbl_name _fk_ N  for naming internally generated foreign keys. This is similar to the pattern used by InnoDB . • Schema and metadata distribution and synchronization.   NDB 8.0 makes use of the MySQL data dictionary to distribute schema information to SQL nodes joining a cluster and to synchronize new 3934
