🔁 Swap Commit Log

0.4.6 (2021-08-11)

This release creates a minimal workflow for dealing with multiple commit log files. On app startup, all outstanding commit logs are replayed and flushed from memtable to SSTable, then deleted. During the course of normal operation, a new commit log is created every time the memtable is flushed, and new writes are routed to that file. The old commit log can be removed right away.
