The pgcopydb clone -follow command implements a full solution for online The pgcopydb follow command implements a logical replication client for Logical Decoding infrastructure and the wal2json plugin. The Change Data Capture facility is implemented using Postgres Pgcopydb implements both the base copy of a database and also Change DataĬapture to allow replay of changes from the source database to the targetĭatabase. Internally so that all indexes may be built concurrently. Also, pgcopydb bypasses pg_restore index building and drives that
Of the process, and implements its own data copying multi-process streaming Given that, pgcopydb then uses pg_dump and pg_restore for the schema parts Work, unfortunately, because pg_dump -format=directory writes to localįiles and directories first, and then later pg_restore -format=directoryĬan be used to read from those files again. The idea would be to use pg_dump -jobs=N -format=directory | pg_restore -jobs=N -format=directory -d in a way. Quickly as possible, one would like to use the parallel options of pg_dumpĪnd still be able to stream the data to as many pg_restore jobs. To make a copy of a database to another server as Pgcopydb is a tool that automates running pg_dump | pg_restore between two
