2ndQuadrant is pleased to announce the availability of pglogical, the next generation in replication systems for PostgreSQL.
pglogical offers Logical Replication as a PostgreSQL extension, which provides the flexibility of trigger-based replication with the efficiency of log-based replication. This ground-breaking new technology has benefits for many key use cases, including:
Existing PostgreSQL users will find the efficiency of pglogical particularly exciting with preliminary testing demonstrating a significant increase in transaction throughput (without lag) over other replication methods. For example, pglogical performed up to 5 times faster than Slony and Londiste3 on OLTP workloads using pgbench
.
