BemiDB is an open-source analytical data warehouse that combines built-in data source connectors (like Fivetran) with a Postgres-compatible OLAP query engine (like Snowflake), syncing data in compressed columnar format to S3. It is packaged as a single Docker image with stateless processes and leverages an Iceberg-based open table format.
Use cases
- centralize data from multiple sources without building ETL pipelines
- run fast analytical queries on Postgres data without impacting production
- query data warehouse with Postgres-compatible BI tools, notebooks, and ORMs
- continuously archive historical data from a Postgres database to S3
- self-hosted Snowflake alternative for a data lakehouse on S3
- sync SaaS data sources like Amplitude, Attio, and Dialpad into a warehouse
When to choose
- you want a self-hosted, open-source alternative to Snowflake plus Fivetran in one tool
- you need Postgres wire compatibility so existing BI tools and ORMs work unchanged
- you want zero-ETL syncing from Postgres or SaaS sources into columnar storage on S3
- you prefer a single Docker image deployment with compute/storage separation
When to avoid
- you need a fully managed cloud data warehouse with elastic multi-node scaling
- you require strict OLTP transactional workloads rather than analytics
- your organization cannot use AGPL-3.0 licensed software
- you need connectors for data sources not yet supported by its built-in syncs
