Reposted by shikharMehul Arora @infiniteregrets.bsky.social · 30/07/2026You can now use S2 as a backend for Mastra Durable Agents! The @ s2-dev/mastra-pubsub adapter maps each durable topic to an S2 stream, with live delivery, replay after refreshes or process restarts, and distributed leases for coordinating thread ownership across processes. 142
shikhar @schmizz.net · 29/07/2026What if your brain could be a pet? @anthropic.com have shared the benefits of decoupling the brain from its hands. We have also written about using a stream per agent session as a WAL and what that unlocks. If it seems complicated, it is. And durable execution frameworks are far too intrusive. 110

shikhar @schmizz.net · 12/07/2026Also considered EFS, inspired by S3 Files being EFS in a trench coat. Built an async Rust lib that lets you use NFS directly from application code. It performs better than a Linux mount, but writes are an order of magnitude slower than what's achievable by purpose-building. Reads look great though. 150

shikhar @schmizz.net · 08/06/2026Serverless gets clowned on sometimes (ha ha, there are servers) but is ultimately about pricing usage and not having to provision resources you don't use, or think about such things as "clusters". It is genuinely hard for stateful services, but I don't think there is a better DevX. 030

shikhar @schmizz.net · 30/04/2026On the retirement of S2's gRPC API, realized how to describe our current API: REST-first. REST undersells, it supports append & read sessions over HTTP/2 similar to gRPC. We'll do HTTP/3 too when the ecosystem is ready. 030
shikhar @schmizz.net · 27/04/2026maybe it's not too surprising plaintext can be competitive with vector dbs when you consider agents effectively do semantic grep by query expansion 020
