Architecture

How flexiq works under the hood — Rust core, scheduler, storage, worker pool.

The internals, explained from the outside in. Start with Overview for the high-level model, then drill into the layer that interests you.

OverviewThe big picture — your language SDK ↔ the Rust core, end to end.Job lifecycleEvery state a job moves through, from enqueue to result or dead letter.Worker poolOS-thread pool, prefork children, async executor — how each model dispatches work.SchedulerThe Tokio polling loop — how jobs are picked, claimed, and routed to workers.StorageThe Storage trait, Diesel for SQLite/Postgres, Redis backend, table schemas.ResourcesThe dependency-injection pipeline — worker injection, scopes, and per-SDK argument handling.Failure modelRetries, dead letters, circuit breakers, cancellation — what happens when things go wrong.SerializationJSON, MsgPack, CBOR, and language-native codecs — how arguments and results cross the worker boundary.
