Essential command-line utilities for mysql.

Overview

maatkit, formerly MySQL Toolkit, is a collection of command-line utilities that provide missing functionality for MySQL. Some of the tools implement lacking server functionality, such as online consistency checks for master/slave replication; others are client-side utilities such as a query profiler.

The following tools are included:

mk-archiver: Archive rows from a MySQL table into another table or a file. See mk-archiver.

mk-checksum-filter: Filter checksums from mk-table-checksum. See mk-checksum-filter.

mk-deadlock-logger: Extract and log MySQL deadlock information. See mk-deadlock-logger.

mk-duplicate-key-checker: Find possible duplicate indexes and foreign keys on MySQL tables. See mk-duplicate-key-checker.

mk-find: Find MySQL tables and execute actions, like GNU find. See mk-find.

mk-heartbeat: Monitor MySQL replication delay. See mk-heartbeat.

mk-parallel-dump: Dump sets of MySQL tables in parallel. See mk-parallel-dump.

mk-parallel-restore: Load files into MySQL in parallel. See mk-parallel-restore.

mk-profile-compact: Compact the output from mk-query-profiler. See mk-profile-compact.

mk-query-profiler: Execute SQL statements and print statistics, or measure activity caused by other processes. See mk-query-profiler.

mk-show-grants: Canonicalize and print MySQL grants so you can effectively replicate, compare and version-control them. See mk-show-grants.

mk-slave-delay: Make a MySQL slave server lag behind its master. See mk-slave-delay.

mk-slave-find: Find MySQL replication slaves and execute commands on them. See mk-slave-find.

mk-slave-move: Move a MySQL slave around in the replication hierarchy. See mk-slave-move.

mk-slave-prefetch: Pipeline relay logs on a MySQL slave to pre-warm caches. See mk-slave-prefetch.

mk-slave-restart: Watch and restart MySQL replication after errors. See mk-slave-restart.

mk-table-checksum: Perform an online replication consistency check, or checksum MySQL tables efficiently on one or many servers. See mk-table-checksum.

mk-table-sync: Synchronize MySQL tables efficiently. See mk-table-sync.

mk-visual-explain: Format EXPLAIN output as a tree. See mk-visual-explain.

Installation

Strictly speaking these tools require no installation; you should be able to run them stand-alone. However, on UNIX-ish systems you can use the standard Perl installation sequence:

   cd <package directory>
   perl Makefile.PL
   make install

System requirements

You need Perl, DBI, DBD::mysql, and some core packages that ought to be installed in any reasonably new version of Perl.
