   Restate✓fullclaimed8/10

   Restate documents immutable deployments and versioning explicitly: in-flight invocations continue running on the code version they started with, and retries are always routed to the same endpoint version, directly addressing safe versioning without breaking determinism (restate-docs-24, restate-docs-41). This is corroborated by broader durable execution guarantees (journal replay, exactly-once) that make this safe. missing for 10: independent/hands-on verification of version-pinning behavior in production, and detail on how new versions are rolled out/deprecated operationally.

   • [claimed-docs] “Restate then makes sure that requests start and end on the same version, by sending any retry attempts always to the same endpoint.”

   DBOS docs explicitly describe versioning and patching as supported strategies for safely upgrading workflow code, and Conductor's console lets you 'version' and 'fork' workflows, directly addressing deploying new code while in-flight workflows continue on their original version. Missing for 10: independent/hands-on confirmation that in-flight runs deterministically finish on the original code version after a deploy, and more detail on how version pinning is enforced at runtime.

   Restate✓fullclaimed8/10

   Restate lets developers write handlers as ordinary code (TypeScript, Java/Kotlin, Python, Go, Rust) using constructs like ctx.run for automatic checkpointing of steps, with no YAML/DSL involved — confirmed by docs on durable steps, durable execution, and SDK support. missing for 10: independent hands-on developer testimony specifically praising 'no DSL/code-first' authoring (community evidence focuses on other aspects like cloud setup and architecture), and no direct comparison showing absence of any config-based workflow definition.

   DBOS workflows are written as ordinary Python/TypeScript functions with annotations, not YAML/DSL, and steps are automatically checkpointed to Postgres for durable recovery, confirmed by docs and community reports of ergonomic, low-code integration. missing for 10: independent third-party benchmark/audit of checkpointing correctness beyond vendor/community anecdotes, and broader language coverage evidence (only Python/TS confirmed).

   Restate~partialclaimed3/10

   Restate's docs describe durable async/sync service invocation, coordination primitives, and event-based signaling that could underlie fan-out patterns, but none of the evidence explicitly documents parallel-step composition, fan-out/fan-in over dynamic batches, or child-workflow invocation as first-class constructs. missing for 10: explicit fan-out/fan-in APIs, dynamic batch parallelism, child/sub-workflow spawning and joining semantics, and any example or docs page dedicated to this composition pattern.

   DBOS docs show the building blocks for this pattern — DBOS.start_workflow to launch child/background workflows and get a handle to wait on results (fan-in), and Queues for running many workflows concurrently with managed concurrency (fan-out over batches) — all without a separate orchestrator, per dbos-docs-5, dbos-docs-6, dbos-docs-26. However, the evidence never explicitly documents parallel-step composition, a dedicated child-workflow API/pattern, or dynamic-batch fan-out/fan-in as a named recipe. missing for 10: explicit child-workflow documentation/pattern, explicit parallel-steps-within-a-workflow guidance, and a concrete fan-out/fan-in-over-dynamic-batches tutorial or example.

Language coverage

   weight 2 · round to Restate
   Restate~partialcommunity6/10

   Restate officially lists five supported SDKs (TypeScript, Java/Kotlin, Python, Go, Rust) covering the mainstream backend languages, and shows some cross-language evidence (Go/Rust client docs, Rust SDK typed ingress clients) alongside deep TypeScript-specific guides for durable steps, timers, error handling, and testing. However, most detailed capability documentation (ctx.run, error handling, testing, AI-assistant integration) is TypeScript-centric, with only shallow mentions for Go/Rust and none for Python/Java, and a community comment notes Go SDK was a later addition, suggesting the SDKs haven't always had lockstep parity. Missing for 10: explicit feature-parity statement across SDKs, equally deep Python/Java/Go documentation, and independent verification that all SDKs support the same primitives (workflows, virtual objects, timers) equivalently.

   DBOS ships and documents both a Python SDK (dbos-transact-py, extensive Python tutorials) and a TypeScript SDK, and its docs show consistent workflow/queue/schedule/communication primitives across at least those two languages, suggesting some cross-language design consistency. However, a community comment explicitly states 'Languages that are supported: Typescript and Python' with no Go or .NET support, directly contradicting the story's expectation of Go (or broader) language coverage, and no evidence documents explicit feature-parity guarantees between the SDKs. missing for 10: Go/other language SDKs, explicit cross-SDK feature-parity documentation, independent confirmation of parity between TS and Python APIs.
