The version 2.0 of pg_chameleon the MySQL to PostgreSQL replica system is now available.

Several improvements come with this new milestone which is compatible with python 3.3+.

  • Replicates multiple MySQL schemas within the same MySQL cluster into a target PostgreSQL database. The source and target schema names can be different.
  • Conservative approach to the replica. Tables which generate errors are automatically excluded from the replica.
  • Daemonised init_replica,refresh_schema,sync_tables processes.
  • Daemonised replica process with two separated subprocess, one for the read and one for the replay.
  • Soft locking replica initialisation. The tables are locked when needed and stored with their log coordinates. The replica daemon puts the database in a consistent status gradually.
  • Rollbar integration for a simpler error detection and alerting.
  • Basic support for the PostgreSQL to PostgreSQL replica (EXPERIMENTAL)
  • Detach replica from MySQL for easy migration to PostgreSQL

Usage examples
