Reset of cache

[SylviaLady]

Since broker version 3.7.15 you introduced the feature of a persistance cache that still survives the restart of the broker.
For components not being the data master of the data distributed this leads to data inconsitencies in our product since we distribute data that is not valid anymore and until the new valid data is available from the data master.

Therefore I would like to reset the cache during restart to avoid that inconsistency. Is this functionality already available since I could not find anything about that till now?
