pg_chameleon is a replication system for replicating MySQL schemas into a target PostgreSQL database.
The latest release is the 2.0.0
pg_chameleon is Python 3.3+ compatible.
The system can read from multiple MySQL schemas and replicate them it into a target PostgreSQL database.
A conservative approach to the replica is implemented. The tables which generate errors during the replay are automatically excluded from the replica.
The init_replica, sync_tables and refresh_schema processes are started in background.
The replica process is fully daemonised with two child subprocesses, one for the read and one for the replay.
pg_chameleon uses a soft approach when initialising the replica . The tables are locked only during the copy. Their log coordinates are used by the replica daemon to put the database in a consistent status gradually.
The system supports the rollbar integration for a better error detection and event monitoring (e.g. when the init_replica ends a message is sent to rollbar).
