Review request for bookkeeper, fpj, Uma Maheswara Rao G, Ivan Kelly, and Rakesh
R.
Description
-------
The current bookkeeper server is single threaded. The same thread handles reads
and writes. When reads are slow (possibly because of excessive seeks), add
entry operations suffer in terms of latencies. Providing separate read and
write threads helps in reducing add entry latencies and increasing throughput
even when we're facing slow reads. Having a single read thread also results in
low disk utilization because seeks can't be ordered efficiently by the OS.
Multiple read threads would help in improving the read throughput.
This addresses bug BOOKKEEPER-429.
