cache

The cache directive controls whether and how task executions are cached.

By default, cached task executions are re-used when the pipeline is launched with the resume option. The cache directive can be used to disable caching for a specific process:

process hello {
    cache false

    // ...
}

See Cache and resume for more information.

The following options are available:

false

Disable caching.

true (default)

Enable caching. Input file metadata (name, size, last updated timestamp) are included in the cache keys.

'deep'

Enable caching. Input file content is included in the cache keys.

'lenient'

Enable caching. Minimal input file metadata (name and size only) are included in the cache keys.

This strategy provides a workaround for incorrect caching invalidation observed on shared file systems due to inconsistent file timestamps.
