Bufstream: A multi-region, active-active Apache Kafka-compatible cluster tested to 100 GiB/s writes and 300 GiB/s reads.

Can you tell the difference between the end-to-end latencies of a multi-region and single-region Bufstream cluster?

On the left is the single-region cluster from our last post.

On the right is a test we completed with 100 GiB/s writes replicated through two (!) cloud regions entirely via GCS.

Bufstream: 100 GiB/s of writes and 300 GiB/s of reads at 350ms latency in GCP.

For a cost that’s literally 25x lower than the cheapest Confluent Cloud offers.

Bufstream’s stateless design gives you all of this, with the operational simplicity that lets you sleep at night.

Using the BSR with Insomnia couldn't be easier - all you need is a BSR API token! Once configured, you can query the BSR for a list of available services and RPCs. Using the schemas provided by the BSR, Insomnia automatically converts binary requests and responses to and from human-readable JSON.
