So coordinator is watching on metadataStore table ( druid_segments table is now empty ) and when the correspondent record referred to segment removed it will initiate historical node to clean the cache and coordinator itself managed by *druid.coordinator.period* and *druid.coordinator.startDelay*.
I have never seen when historical drop the cache.
Is there any way to check it?
Thank you.
