Roman Puchkovskiy updated IGNITE-26117:
---------------------------------------
Description:
There are two ways to destroy a Raft group storages (namely, log storage and
Raft meta storage): durable and non-durable. Durable version makes sure that,
if the call returned, then the destruction will complete if it was not able to
finish its job (for example, due to node crash). Durable destruction is more
costly as it requires to write destruction invent to the Vault (and this does
an fsync). Currently, both when destroying a table as a whole and when
destroying just one partition of a table, we use durable Raft storages
destruction.
But after IGNITE-25621, durability guarantee becomes redundant for Raft
storages destruction done when destroying whole tables as the mechanism
introduced in IGNITE-25621 provides its own guarantee on a higher level.
Hence, we should now have a separation:
# When just a single partition is destroyed (due to eviction from node), its
Raft storages should still be destroyed durably
# When whole table is destroyed, Raft storages of its partitions should use
non-durable destruction
> Use non-durable Raft storages destruction for table destruction
