Restate

?? From real-time analytics to transactional magic – what comes after Apache Flink? If you’ve ever wondered how to take event-driven architecture to the next level, this talk is for you. ?? ?? Stephan Ewen, founder of Restate and co-creator of Apache Flink, joins Data & AI Warsaw Tech Summit 2025 to present a powerful evolution in stream processing: "From Apache Flink to Restate – event-driven applications from analytics to transactions". What to expect? ? How Restate brings transactional guarantees to event-driven systems – perfect for sagas, AI agents, and orchestrated microservices ?? ? Why durable execution is the next frontier beyond stream processing ?? ? What lessons from Flink shaped Restate's low-latency, serverless-first architecture ?? Built by the minds behind Flink, Restate trades raw throughput for flexibility, resilience, and ultra-fast transactional flows. Think OLTP for the world of events. ? When?

On March 27th AxonIQ and Restate will conduct a webinar on implementing CQRS and Event Sourcing in the context of durable execution. I and Giselle van Dongen will explore the following topics: ?? Using Restate Virtual Objects for encapsulating event-sourced command models, creating projections and handling queries. ?? Combining event processing in Restate with an external event store (Axon Server). ?? Evolving Axon Framework Sagas with Restate’s ”workflow as code”.? ?? Building projections across multiple workflows. For event-driven practitioners interested in or already using Restate / Axon, this webinar is for you!

In our last community meeting, we had an introduction to the brand-new Restate UI with Nikrooz Nasr. The UI lets you manage, configure, understand, and debug applications. Follow the quickstart to get the UI running locally: https://lnkd.in/dqygi8VK Watch it here: https://lnkd.in/d5ia3iwh

Restate v1.2.2 has been released ?? It comes with various fixes and quality of life improvements: * Improved partition processor and invoker observability (lag between applied index and log tail) * Restatectl improvements * Creating snapshots if minimum LSN is reached * Trim the log after creating snapshots * Safety checks when changing the log server state * Various UI improvements and fixes * Automatic log chain trimming to prevent unbounded growth Grab it while it's ?? https://lnkd.in/eyWd2XnM

Two new entries in https://lnkd.in/dcPqZeAS - from Restate The Anatomy of a Durable Execution Stack from First Principles(Thank you Stephan Ewen, Till Rohrmann and Ahmed Farghal) - from Hatchet: Understanding Durable Executions in Hatchet

See Restate 1.2 in action in last week's community meeting. Ahmed Farghal and Till Rohrmann introduced Restate's distributed design and showed demos of high availability and scaling your clusters. Check it out here: https://lnkd.in/dTyhMwah And let us know what you think!

Restate 1.2 is out! Join the community meeting to learn more about Restate's internals and to see demos about Restate clusters and the UI. Sign up here: https://lu.ma/spmijmoa

For your weekend read: We released ?????????????? ??.?? this week ???? A ?????????????????????? ?????????????? ?????????????????? ??????????????, ???????? ?????????? ???????????????????? A ????????????-??????????????????, ??????????????????????????, ????????????????, and ?????? ?????????????? runtime in a ????????-?????????????????? ???????????? that scales from your laptop to complex distributed deployment. Making the capabilities of durable functions and workflows available to ???????????????? and ??????????????-?????????????????? apps, services, and serverless functions. Read here how it works: https://lnkd.in/egdnAAVG I have rarely been more proud than I am of what this incredible team has built here. ?? Restate ??????????'?? ???????? ?????? ????????????????, ??????, ???? ?????????????? ????????????????????. Just start the runtime, cluster it, and get a system with amazing resilience, flexibility, simplicity. Point it to an object store for efficient failover. Restate is openly available at https://lnkd.in/ewjmabfK To get there, we re-imagined a runtime for durable execution from first principles, because we don't believe this amazing experience would have been possible with anything less: * The architecture ???????????????? ???????????? ???????????? (like S3) for bulk data storage, but fronts it with ?? ??????-?????????????? ?????????????????????? ?????????? to offer very low latency for the durable functions and workflows. * That also means it runs anywhere you have an object store (cloud, on-prem) and ???????? ?????????? ???????????? ???????? ??????????????. It of course still runs on your laptop or as a single node with persistent volume. * We built ?????? ?????? ?????????????????????? ?????? ???????? ?????? ?????????????? (single round trip, quorum replication with external consensus), durability (active-active with flexible quorums), and flexibility (segmented log that can be dynamically reconfigured) - it competes with the best open-source log implementation out there * The execution/orchestration is a stream-processing-like architecture with ?????????????????????????? ????????????????????: Strong consensus on every operation ensures Restate never loses or duplicates a committed step, state update, or violate idempotency keys, regardless of failures, network partitions, or split brains. At the same time, Restate keeps the latency overhead for that low. * The log is based on a ?????????????? ?????? design with external consensus, to make it possible to support different setups blending replication and object storage in various ways. * You can run it ?????????????????? (???????????? ????????????) and just start multiple nodes. Or you can run ?????????????????????????? ?????????????????????? where you separate the control plane, log, and processor (orchestrator) for maximum flexibility - for example for platform teams.

? Restate 1.2 includes a ???????????????? ?????????????????? ???? that lets you manage, configure, understand, and debug applications.
