Add a configuration property for socket receive buffer size for replication
endpoints
-------------------------------------------------------------------------------------
Key: HBASE-3473
URL: https://issues.apache.org/jira/browse/HBASE-3473
Project: HBase
Issue Type: Improvement
Components: replication
Reporter: Gary Helmling
Priority: Minor
Looking at this blog post about optimizing replication throughput for
LinkedIn's Kafka:
http://sna-projects.com/blog/2011/01/optimizing-tcp-socket-across-data-centers/
It seems worth testing out if HBase replication connections can also benefit
from increasing the socket receive buffer size on (expected to be) high-latency
connections.
To this end, we would add a new configuration property for receive buffer size
for replication connection and do some benchmarking to evaluate throughput with
different values, verifying that making this configurable would have
significant impact. For the moment, it seems best to scope the configuration
setting to replication connections only, in order to avoid also impacting
(negatively) intra-cluster communications.
