I really like what S2 is doing: s2.dev/blog/agent-sessions , looking for more examples like this!

Stream per agent session

Why AI agent sessions need their own durable streams for memory, auditability, isolation, branching, and reliable resume.

"We use a durable stream built on top of object storage called s2.dev: every chunk appended to it receives a sequence number, so in chat.agent reconnecting with the last one you saw is built in." @triggerdotdev knows the real deal about building chat agents 😍

Durable streams API · S2

S2 is the serverless API for durable streams: unlimited, real-time, built for AI agents and event streaming. Append, read from any point, or follow live.

7 things we wish we'd known before building our first production chat agent tgr.dev/ELpr671

7 things we wish we'd known before building an AI chat agent | Trigger.dev

We built a chat agent for our developer dashboard and wanted it to be really really good. Seven tips we learned along the way: fast first replies, compaction, retries, resumable streams, prompts,...

I love this. I have a crapton of agent generated data I need to stream out to the cloud. But what I really like about this is that it's a known interface, anyone can run redis, but then I can get magical cloud based for larger setups and usecases.

we power streams for both the brain (agent WALs) and the hands (real-time telemetry)

Durable streams with the paperwork to match. We are now SOC 2 Type II compliant, alongside HIPAA and GDPR. After 3 months of observation, an independent pentest, and a controls audit by Prescient Security with @Oneleet. Reports/BAA/DPA email: [email protected]

with WAL on S3 being the hot topic, i think the architecture behind @s2_streamstore is pretty fucking cool!

S2 @s2_streamstore is goated, using it to back a time travel filesystem we’re building

we have invested in Deterministic Simulation Testing since day 1, tune in to @sgbalogh0 talk about it with @AntithesisHQ!

Only a few hundred developers have ever built a deterministic simulation testing rig, and of those, vanishingly few have used both a homegrown system and Antithesis. Full video: youtu.be/PbCo59hLcFo

Deterministic simulation testing: Build or buy?

So you've heard of this amazing testing approach called determinist...

Testing is often perceived as a quality concern, but the fastest startups out there know that good testing actually drives velocity as well. Here's @sgbalogh0 of@s2_streamstore on camera. @erscio, @archildata, @paradedb, and many others are also shipping faster with Antithesis. And now @AWSActivate is making Antithesis more accessible than ever, with a special discount for startups building on @awscloud.

Durable streaming powered by @s2_streamstore 🤩 Awesome ship by the @triggerdotdev team

We spent the last 6 months building our take on a chat agent SDK. It’s open source and uses the stateful compute that powers our existing tasks and workflows.

and @s2_streamstore is the serverless log primitive that was missing

everything that can be will be converted into `state = memo { f(log) }` all other state management is just too complex at the limit

Killer product, I used it once and thought "ok I can trust this for a long time"

Something new we've been cooking on: 🍳 Overeasy: A durable filesystem overlay, backed by immutable logs on S3 Overeasy makes your FS: - forkable - resumable across machines (demo 👇) - revertible to any prior state
