Andrew Purtell commented on HBASE-2315:
---------------------------------------
@Flavio: Thanks for your kind reply.
bq. In fact, with a previous version of BK, we were able to get 70kwrites/s for
writes of 128 bytes
Dedicated hardware, I presume. How many BK nodes would be needed alongside
HBase+Hadoop nodes to achieve 1M ops/sec over 100 concurrent ledgers? HBase WAL
has group commit but that can only batch so much... depends on the order of
edits coming from userland. So what amount of batching? (Average transaction
size to BK for example.)

> BookKeeper, a contrib of the ZooKeeper project, is a fault tolerant and high
> throughput write-ahead logging service. This issue provides an implementation
> of write-ahead logging for hbase using BookKeeper. Apart from expected
> throughput improvements, BookKeeper also has stronger durability guarantees
> compared to the implementation currently used by hbase.
