Running the samples that use redis where workers are separate generates non-stop errors like the following: 2025/09/15 23:01:02 ERROR error polling task error="dequeueing task: NOGROUP No such key 'task-stream:system:activities' or consumer group 'task-workers' in XREADGROUP with GROUP option" The original error occurred because: * The worker tries to recover abandoned tasks during startup using XAUTOCLAIM * This requires existing consumer groups for the Redis streams * Previously, consumer groups were only created when PrepareWorkflowQueues/PrepareActivityQueues were explicitly called * The recovery operations happened before queue preparation, causing NOGROUP errors The fix ensures that consumer groups for the essential queues (default and _system_) are created automatically during Redis backend initialization, eliminating the race condition.
