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. QQ: ensure opened segments are closed after some time of inactivity 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.
from rabbit_fifo version 0. QQ: avoid dead lock in queue federation. When processing the queue federation startup even the process may call back into the ra process causing a deadlock. in this case we spawn a temporary process to avoid this.
