MySQL Super Dump

MySQL Super Dump is a tool to efficiently create filtered and manipulated database dumps. It relies in the power of the SQL native language to do this, using WHERE clauses and complete SELECT statements with aliases to do this.

Currently it does not support every kind of MySQL structure (views, triggers, etc), but it supports the most basic stuff: schemas, tables and rows.

History

Once uppon a time there was a development team that liked to use dumps from the production database in their development environments to have the same content and behavior of the production system in their machines.

To avoid security problems, the system administrator created a script to dump the production database, import in a temporary database, then replace all sensitive data, like salts, passwords, customer names, emails, etc, for fake data, then export a dump of this temporary database to a file that is the dump developers would use.

However this script was taking more time to run, day by day, and each day it was using more resources from the server to run, until it exploded.

Features

• Filter dumped rows by a native WHERE clause ([where] config's section)
• Replace dumped data with native SELECT functions ([select] config's section)
• Disable data output of specific tables ([filter] config's section: nodata)
• Ignore entire tables ([filter] config's section: ignore)

Usage

• Install the latest Go compiler installed (check instructions at: http://golang.org)
• Check you environment with go env:
• The repository will be clones at $GOPATH/src/github.com/hgfischer/mysqlsuperdump
• The binary will be installed in $GOBIN
• Then run go get to download, build and install mysqlsuperdump: go get github.com/hgfischer/mysqlsuperdump
• Create a config file based on example.cfg and place where you like it.
• Run mysqlsuperdump -h to see command line options and voilá.

TO DO

• Extend MySQL support, with other objects like views, triggers, etc
• Refactor dumper interface to support another SQL databases
• Add support for PostgreSQL
