MySQL Server offers a number of choices in storage engines. Since both NDB and InnoDB can serve as transactional MySQL storage engines, users of MySQL Server sometimes become interested in NDB Cluster. They see NDB as a possible alternative or ...
https://dev.mysql.com/doc/refman/5.7/en/mysql-cluster-limitations-database-objects.html
Some database objects such as tables and indexes have different limitations when using the NDBCLUSTER storage engine: Database and table names. When using the NDB storage engine, the maximum allowed length both for database names and for table ...

Reads a redo log file, checking it for errors, printing its contents in a human-readable format, or both. ndb_redo_log_reader is intended for use primarily by NDB Cluster developers and Support personnel in debugging and diagnosing problems. This ...
21.7.9.1 NDB Cluster Replication: Automating Synchronization of the Replica to the Source Binary Log
https://dev.mysql.com/doc/refman/5.7/en/mysql-cluster-replication-auto-sync.html
It is possible to automate much of the process described in the previous section (see Section 21.7.9, “NDB Cluster Backups With NDB Cluster Replication”). The following Perl script reset-replica.pl serves as an example of how you can do this.
https://dev.mysql.com/doc/refman/5.7/en/mysql-cluster-replication-general.html
A replication channel requires two MySQL servers acting as replication servers (one each for the source and replica). For example, this means that in the case of a replication setup with two replication channels (to provide an extra channel for ...

MySQL includes two plugins that implement native authentication; that is, authentication based on the password hashing methods in use from before the introduction of pluggable authentication. This section describes mysql_native_password, which ...
https://dev.mysql.com/doc/refman/5.7/en/nested-loop-joins.html
MySQL executes joins between tables using a nested-loop algorithm or variations on it. Nested-Loop Join Algorithm Block Nested-Loop Join Algorithm Nested-Loop Join Algorithm A simple nested-loop join (NLJ) algorithm reads rows from the first table ...
https://dev.mysql.com/doc/refman/5.7/en/not-enough-file-handles.html
If you get ERROR 'file_name' not found (errno: 23), Can't open file: file_name (errno: 24), or any other error with errno 23 or errno 24 from MySQL, it means that you have not allocated enough file descriptors for the MySQL server. You can either ...
https://dev.mysql.com/doc/refman/5.7/en/optimize-overview.html
Database performance depends on several factors at the database level, such as tables, queries, and configuration settings. These software constructs result in CPU and I/O operations at the hardware level, which you must minimize and make as ...

These performance tips supplement the general guidelines for fast inserts in Section 8.2.4.1, “Optimizing INSERT Statements”. When importing data into InnoDB, turn off autocommit mode, because it performs a log flush to disk for every insert.
