EDB Postgres Distributed (PGD)
==============================

DB Postgres Distributed (PGD) provides multi-master replication and data
distribution with advanced conflict management, data-loss protection,
and `throughput up to 5X faster than native logical replication <https://www.enterprisedb.com/blog/performance-improvements-edb-postgres-distributed>`_  . It enables distributed Postgres clusters with high
availability up to five 9s.

By default, EDB Postgres Distributed uses asynchronous replication,
applying changes on the peer nodes only after the local commit. You can
configure additional levels of synchronicity between different nodes,
groups of nodes, or all nodes by configuring `Synchronous Commit <https://www.enterprisedb.com/docs/pgd/latest/commit-scopes/synchronous_commit/>`_  ,
 `Group Commit <https://www.enterprisedb.com/docscommit-scopes/group-commit>`_  (optionally with :ref:`Eager conflict resolution <Eager conflict resolution>`  ), or :ref:`Commit At Most Once <Commit At Most Once>`  .
