Bufstream is the Kafka-compatible message queue built for the data lakehouse era.
Store directly to Apache Iceberg tables and slash cloud costs 8x with Bufstream, a drop-in replacement for Apache Kafka.
Overview
Bufstream is the Kafka-compatible message queue built for the data lakehouse era. It's a drop-in replacement for Apache Kafka, but instead of requiring expensive machines with large attached disks, Bufstream builds on top of off-the-shelf technologies such as S3 and Postgres to provide a Kafka implementation that is built for 2025.
Bufstream is entirely self-hosted in your AWS instance. Refer to our Bufstream Docs (https://buf.build/docs/bufstream/cost/Â ) for more detail on AWS infrastructure costs you will require.
Disclaimer: not meant to be purchased without first contacting a Buf representative.
Highlights
- 8x lower cloud costs: Bufstream replaces traditional disks with object storage, the most reliable and cost-effective cloud storage primitive. By eliminating expensive network-attached volumes and delegating cross-zone data replication to object storage Bufstream reduces cloud costs 8x compared to Apache Kafka, while remaining fully compatible with Kafka clients, connectors, and tools.
- Apache Iceberg as your Kafka storage layer: Bufstream natively writes your data to S3-compatible object storage as Iceberg tables with zero copies. Eliminate the need for a costly ETL pipeline and start querying your data in seconds.
- Guaranteed data quality: Bufstream eliminates bad data at the source: rather than hoping that every producer will opt into validation, Bufstream agents work with the Buf Schema Registry to enforce quality controls for all topics with Protobuf schemas. Bad data is immediately rejected, so consumers can trust that the data they receive will always match the appropriate schema and adhere to any semantic constraints.
