Deprecated Variations
Group Name
DEFAULT task_time_to_live
task_executor
Type:string
Default:taskflow

Specifies which task executor to be used to run the task scripts.

work_dir
Type:string
Default:<None>

Work dir for asynchronous task operations. The directory set here will be used to operate over images - normally before they are imported in the destination store. When providing work dir, make sure enough space is provided for concurrent tasks to run efficiently without running out of space. A rough estimation can be done by multiplying the number of max_workers - or the N of workers running - by an average image size (e.g 500MB). The image size estimation should be done based on the average size in your deployment. Note that depending on the tasks running you may need to multiply this number by some factor depending on what the task does. For example, you may want to double the available size if image conversion is enabled. All this being said, remember these are just estimations and you should do them based on the worst case scenario and be prepared to act in case they were wrong.

taskflow_executor
