Summary

PeerDB streams data from Postgres to data warehouses, queues and storage engines. It supports log-based change data capture, cursor-based replication using timestamps or integers, and XMIN-based replication. A Postgres-compatible SQL interface supports ETL and data movement, while Postgres features include jsonb, arrays, PostGIS, TOAST columns and schema changes. PeerDB lists PostgreSQL, MySQL, MongoDB, CockroachDB and BigQuery as actively maintained source connectors. Its actively maintained destinations are ClickHouse, ClickHouse Cloud and Postgres; Snowflake, BigQuery, Elasticsearch, Kafka, Redpanda, Confluent, Azure Event Hubs, Google Pub/Sub and S3 destinations are deprecated and no longer actively maintained. The software is available for free under the AGPL-3.0 license, with a Docker container setup and CDC, streaming query and query layer features. Paid plans start at $250/mo. PeerDB states that it is 10x faster than existing tools and says it has SOC 2 Type II and GDPR compliance. Documentation and community Slack are available; paid plans include implementation support, and certain plans offer 24x7 production support with SLAs.
