Vladislav Pyatkov updated IGNITE-16444:
---------------------------------------
Description:
The protocol of the storage requires determining the earliest revision
(_RocksDbKeyValueStorage#earliestRev_), but current implementation of the
compact method does not allow defining it. Because after the compact is
invoked, it removes all value old values.
was:
Metastorage has a method _KeyValueStorage#compact_ for removing absolute
history. But today the compaction leads to holes in Metastorage history. It
makes impossible to seek the earliest revision value
_RocksDbKeyValueStorage#earliestRev_.
The mechanism requires of correction that the history has no holes after
compaction.
Also, the logic for updating the earliest revision value should be implemented.
> The Compact method is not math to protocol of RocksDbKeyValueStorage
