No, deploying more than one Temporal instance is not the recommended solution for handling worker failures during sync. Instead, you should consider increasing the number of replicas for the

airbyte-worker

deployment and setting the values for

TEMPORAL_WORKER_PORTS

,

MAX_SPEC_WORKERS

,

MAX_CHECK_WORKERS

,

MAX_DISCOVER_WORKERS

, and

MAX_SYNC_WORKERS

variables in the worker pod deployment. This will help you manage the parallelism and resource allocation for your sync jobs more effectively [^1^]. [^1^]: https://airbytehq.slack.com/archives/C021JANJ6TY/p1677491714222019
