Documentation

Mysql2pg copies records from MySQL tables to existing PostgreSQL tables.

Mysql2pg also resets sequences, based on the maximum column value.

Performance is limited by network bandwidth, database resources, record size, and parallelism. In anecdotal usage, performance is 500k records/min serially.

Supported

• Parallelism
• Foreign keys
• PostgreSQL schema

Not supported

• Creating PostgreSQL tables. If you need to convert schema, look at other tools like mysql2postgres.
• Limiting the tables.

Implementation

1. MySQL tables are discovered.

2. PostgreSQL tables are truncated.

3. PostgreSQL triggers (including foreign keys) are disabled.

4. Records are streamed from MySQL and uploaded to PostgreSQL via the COPY command.

5. Sequences are discovered and reset based on the maximum value in the column.

Tables are processed in parallel.
