The following table describes each of the major quotas, limits, defaults, and throttles in Azure Scheduler.
| Resource | Limit Description |
|---|---|
| Job size | The maximum job size is 16K. If a PUT or a PATCH operation results in a job size larger than this limit, a 400 Bad Request status code is returned. |
| Job collections | The maximum number of job collections per Azure subscription is 200,000. |
| Jobs per collection | By default, the maximum number of jobs is five jobs in a free job collection and 50 jobs in a standard job collection. You can change the maximum number of jobs on a job collection. All jobs in a job collection are limited to the value set on the job collection. If you attempt to create more jobs than the maximum jobs quota, the request fails with a 409 Conflict status code. |
| Time to start time | The maximum "time to start time" is 18 months. |
| Recurrence span | The maximum recurrence span is 18 months. |
| Frequency | By default, the maximum frequency quota is one hour in a free job collection and one minute in a standard job collection. You can make the maximum frequency on a job collection lower than the maximum. All jobs in the job collection are limited to the value set on the job collection. If you attempt to create a job with a higher frequency than the maximum frequency on the job collection, the request fails with a 409 Conflict status code. |
| Body size | The maximum body size for a request is 8192 chars. |
| Request URL size | The maximum size for a request URL is 2048 chars. |
| Header count | The maximum header count is 50 headers. |
| Aggregate header size | The maximum aggregate header size is 4096 chars. |
| Timeout | The request timeout is static (not configurable) and is 60 seconds for HTTP actions. For longer running operations, follow the HTTP asynchronous protocols. For example, return a 202 immediately but continue working in the background. |
| Job history | The maximum response body stored in job history is 2048 bytes. |
| Job history retention | Job history is kept for up to 2 months or up to the last 1000 executions. |
| Completed and faulted job retention | Completed and faulted jobs are kept for 60 days. |
