How AI describes Bufstream

Bufstream is a drop-in replacement for Apache Kafka that stores streaming data directly as Apache Iceberg tables in S3-compatible object storage, eliminating the need for ETL and letting you start querying in seconds. It guarantees data quality by routing all topics through the Buf Schema Registry to enforce Protobuf schemas and semantic constraints, rejecting bad data at the source. The solution emphasizes cost and security, delivering about 8x lower cloud costs with object storage, enabling fully air-gapped deployments in AWS or GCP VPC, and offering field-level RBAC.
