Data workflows service limitations
The table row Task input/output size limit applies to the input and output of a workflow task. A process triggered by a workflow task, such as a Cognite Function, may have different limits for parameters and inputs. For an overview of limits across CDF services, for example Cognite Functions, see CDF service limits.| Name | Limit per CDF project |
|---|---|
| Workflows | 1000 |
| Workflow definitions | 1000 |
| Total number in a single workflow execution, including tasks generated by dynamic tasks | 200 |
| Concurrent workflow executions (system-wide) | 50 |
| Maximum concurrent runs per workflow (user-configurable) | User-defined |
| Concurrent workflow task executions | 50 |
| Task input/output size | 0.2 MB |
| Triggers | 200 |
You can configure the maximum concurrent runs for each individual workflow to control resource usage and ensure predictable processing. This limit operates within the system-wide concurrent execution limit. See Use data workflows for configuration details.
Workflow execution limitations
- Dynamic tasks can’t include new dynamic tasks or subworkflow tasks.
- Subworkflow tasks can’t include dynamic tasks or new subworkflow tasks.
- The maximum duration of a workflow execution is 24 hours.
- Workflow execution data is stored for three months, unless the total size of the execution payload exceeds 20MB.
