This version of Ra contains a substantially refactored Ra log implementation that provides higher throughput and lower memory use in serveral scenarios.
This offloads the work of reading messages from on-disk segments to the interacting process rather than doing this blocking, performance affecting work in the ra server process.
If a channel/session process has opened a segment that later was appended to the index maintained in memory does not know of the newly appended entries and thus would generate a missing_key error.
Processes that havea received messages that had to be read from disks may keep a segment open indefinitely. This introduces a timer which after some time of inactivity will close all opened segments to ensure file desciptors are not kept open indefinitely.
