Workers, Durable Objects - Durable Objects can use up to ten Dynamic Workers concurrently

UpdateAug 28, 2026·Unverified·Added Sep 24, 2026

Durable Objects can have up to ten distinct Dynamic Workers with in-flight requests, increased from four. This limit applies across all concurrent requests to the same Durable Object because they share an input/output (I/O) context. Other Workers can have up to four distinct Dynamic Workers with in-flight requests per request.
