Added two new settings to control insertion behavior when there are too many inactive parts in MergeTree tables.
Why it matters
This feature addresses situations where the server fails to clean up inactive parts quickly enough, which can lead to an excessive number of inactive parts accumulating. By allowing users to delay insertions or throw errors when this condition is detected, it helps maintain system stability and prevents uncontrolled growth of inactive parts.How to use it
Users can enable these settings by configuring the new parameters that delay insertion or cause an insertion to fail when the number of inactive parts exceeds a threshold. This is done by setting the appropriate configuration options before performing inserts.
