NAME
maatkit - Essential command-line utilities for MySQL.

DESCRIPTION
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.

SEE ALSO
See also the maatkitdsn documentation, which explains how to use DSNs to connect to MySQL.

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.

If you find bugs, need features, etc please use the bug tracker, forums, and mailing lists at http://sourceforge.net/projects/maatkit.
