pool.ddt_prefetch
=================

Prefetch DDT entries in pool ``pool_name``.

.. versionremoved:: 26
    Use :doc:`pool.prefetch <api_methods_pool.prefetch>` instead, which prefetches both DDT and BRT metadata.

This method is a job.

*DEPRECATED: this method is scheduled to be removed in v27.*
