|
username: sa_ka_na
In the implementation of tinykv, if at some point it is found that applied index - storage first index > gcLimit, a Log Compact Request will be proposed to the Raft layer. After it is committed, the gc worker is notified to perform log compaction.
Why is it necessary to reach consensus before performing log compaction, rather than having each peer do it individually?
