cache

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

Usage

By default, cached task executions are reused when the pipeline is launched with the resume option. Use the cache directive to disable caching for a specific process:

process hello {
    cache false

    // ...
}

See Cache and resume for more information.

Options

The following values are available:

false

Disable caching.

true (default)

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

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