.. _deleting:

Moving data to recycle bin
==========================

On the same frequency as the storage usage checks, the Buffer Manager will also look
for any Flow entries that match the following criteria and mark them for "DELETING".

- All the dependencies on a flow are in ``FINISHED`` state.
- The state is in ``COMPLETED``, ``INCOMPLETE``, or ``FAILED``.
- The Flow's ``expiry_time`` entry is set (and is positive).
- And that the ``last_updated + expiry_time`` is in the past.

In addition, it also periodically checks data-product flows and moves data
associated with the ones in ``DELETING`` state to a "recycle bin",
which is a reserved area in the data PVC. Once a data product is in the "recycle bin",
the state of its associated flow is set to ``DELETED``.

Users can then go to the ``recycle_bin`` directory
and delete the data products manually if they are no longer needed.
