pgcopydb (PostgreSQL specific): Zero Downtime : Uses PostgreSQL logical replication slots to copy table data and catch up on concurrent live changes.
Loading…
pgcopydb is a tool that automates copying a PostgreSQL database from one running server to another by coordinating parallel pg_dump and pg_restore and streaming data to multiple restore jobs. It supports both a base copy and Change Data Capture to replay source changes on the target, using PostgreSQL's logical decoding (default pgoutput) and plugins such as test_decoding and wal2json. WAL changes are recorded in SQLite databases within the work directory to enable restart/resume, rotation, and pruning, and the project includes commands like follow and clone --follow for online migration with continuous replication and concurrent index builds.
