What PeerDB is

PeerDB streams data from Postgres to data warehouses, queues, and storage engines through one-way replication. It supports log-based change data capture, cursor-based replication using timestamps or integers, and XMIN-based replication, with a Postgres-compatible SQL interface for ETL and data movement. PeerDB lists PostgreSQL, MySQL, MongoDB, CockroachDB, and BigQuery as actively maintained source connectors; its actively maintained destinations are ClickHouse, ClickHouse Cloud, and Postgres. Support for Postgres data types such as jsonb, arrays, and PostGIS extends to TOAST columns and schema changes. The software is available to use and deploy under the AGPL-3.0 license. The Open source plan is free; paid plans start with Micro at $250 a month. Several destinations, including Snowflake, BigQuery, Elasticsearch, Kafka, Redpanda, Confluent, Azure Event Hubs, Google Pub/Sub, and S3, are deprecated and no longer actively maintained. PeerDB states that it is 10x faster than existing tools and that it has SOC 2 Type II and GDPR compliance.

Who it suits

PeerDB suits teams moving data from supported databases into actively maintained destinations, particularly those seeking Postgres-focused replication options. Its free deployment option may suit individuals; paid plans offer implementation support, with certain plans including 24x7 production support and SLAs.
