zhaijia updated BOOKKEEPER-827:
-------------------------------
Description:
Current bookie compaction in GarbageCollector has two settings:
'compactionMaxOutstandingRequests' and 'compactionRate'. They are throttling
and limiting the compaction by entries.
But from a bandwidth perspective, it would be good that we could throttle and
limit compaction by bytes, which would really reflect the bandwidth of disk.
So in this enhancement, we added another "by bytes" option when doing
compaction in GarbageCollector:
"boolean isThrottleByBytes": true when use by bytes, false when use by entries;
"int maxOutstandingRequests": by entries, number of entries before flush.
"int compactionRate": by entries, number of entries ;
+ final int maxOutstandingRequestsBytes;
+ final int compactionRateByEntries;
+ final int compactionRateByBytes;
