Summary
Fixes #5575
When Azure Batch hits the active job and schedule quota (HTTP 409
ActiveJobAndScheduleQuotaReached), Nextflow now retries with configurable backoff instead of failing immediately.Changes
AzBatchService.groovy: AddedapplyCreateJob()using FailsafeRetryPolicywith a fixed delay to handleActiveJobAndScheduleQuotaReachedquota errors. This layers on top of the existingapply()method —apply()handles short-lived transient errors (408, 429, 500, etc.) whileapplyCreateJob()handles the longer-lived quota exhaustion with configurable fixed delays. ExtractedcreateJobRequest()andisJobQuotaError()as protected methods for testability.AzBatchOpts.groovy: Added two new config options:azure.batch.maxJobQuotaRetries(int, default3) — maximum number of retries when quota is reachedazure.batch.jobQuotaRetryDelay(Duration, default2 min) — delay between retriesAzBatchServiceTest.groovy: Added 6 unit tests covering: success on first try, retry then succeed, exhaust retries, zero retries, non-quota 409 errors, and non-HTTP exceptions.Behavior
When job creation fails with
ActiveJobAndScheduleQuotaReached:Azure Batch active job quota reached - waiting 2m before retry (attempt 1 of 3)IllegalStateExceptionis thrown with a helpful message suggesting config changes
