Description
PicoMQ is a Rust server for Durable Streams, built on Object Store. Cheap, URL-addressable, granular streams (create/append/read/long-poll/SSE), with Pico Protocol or Durable Streams Protocol as the facade.S3Stream is the stream storage primitive, used in AutoMQ, shipped as a Rust library. Coordination is a command log in Postgres.

Could you build this?
No Implementing a durable streaming engine directly on object storage requires world-class distributed systems and low-latency storage primitives engineering.
What it would actually take: Requires building an asynchronous I/O engine in Rust (using Tokio) that abstracts append-only commit logs directly over S3 multipart uploads. It demands implementing distributed lease management/consensus for partition ownership, sophisticated read-ahead and write-back caching to mask object store latency, and zero-disk garbage collection protocols.
Discussion
20 comments analyzed.
Competitors mentioned: Apache Kafka, AWS Kinesis, AutoMQ, WarpStream, S2/S2-lite
Concerns raised: Cold-start latency for WAL recovery during rapid scaling to zero, Lacks batching, caching, and low-latency benefits of fully serverless systems, Not suitable for very high-scale traffic (GBs/sec+) or ultra-low latency (microseconds) use cases, Limited project maintenance and developer attention, Durability ACK latency higher than systems with local consensus (vs S3-dependent)
Feature requests: Disk/EBS-staged WAL for lower-latency durability ACKs, GCP deployment example with Rapid Bucket support, Kafka wire protocol support with restrictions (single partition, no transactions), FAQ section clarifying when PicoMQ is not suitable replacement for Kafka
