Could you build this?

No A durable execution engine in Rust requires provable determinism, event sourcing, transaction isolation, and crash recovery that vibe coding cannot safely construct.

What it would actually take: Implemented in Rust using SQLite or PostgreSQL as the append-only event store, paired with a deterministic state machine replay engine and concurrent task scheduler. The critical challenge is ensuring replay determinism across worker crashes, preventing race conditions during task heartbeating, and optimizing event compaction. Requires deep expertise in distributed systems, database transaction semantics, and concurrent systems programming in Rust.

Discussion

5 comments analyzed.

Competitors mentioned: Temporal, Airflow, Prefect, Dagster, Effect-ts

Concerns raised: Retry layer ignores WAIT signal during rate-limit windows, causing loops to fail, Not battle-tested at Temporal scale, Steep learning curve compared to declarative alternatives, Requires understanding of determinism constraints, Limited production-tested monitoring (Prometheus metrics, structured logs, audit logs not well tested yet)

Feature requests: Visual workflow builder with better UX than standard tools, Expand template marketplace for non-technical users, More pre-built templates for common workflows
