PicoMQ
1 commentThe first launch from PicoMQ
PicoMQ keeps a durable message stream on S3-compatible object storage and serves it over plain HTTP. There is no broker cluster to run and no separate storage tier to size: the bucket is the log, and clients read and write it over a protocol that already crosses every network you have.

Half the systems I have seen running Kafka are moving a few thousand messages a minute and paying for a cluster because that is what you do. This is the other end of that trade: the durability comes from the object store, which somebody else is already keeping alive.
HTTP as the transport is the part I keep thinking about. It means the stream works from a browser, from a lambda, and through whatever proxy your company insists on. Latency is the obvious question — worth asking the author what it looks like under load.
