Roman Puchkovskiy updated IGNITE-25540:
---------------------------------------
Description:
Users need a possibility to push LWM up to trigger removal of overwritten tuple
versions and destruction of dropped tables/zones.
The push can be soft and hard. This issue is about the soft variant where new
LWM is just proposed, so RO transactions reading at timestamps below the
proposed timestamp are allowed to finish before the LWM gets actually raised.
We need to design endpoints (SQL query, REST API, CLI?) that would be used to
trigger the soft LWM raise, and implement them.
