---------------------------------
Summary: HBaseServer shall read and deserialize data from each
connection in parallel
Key: HBASE-6103
URL: https://issues.apache.org/jira/browse/HBASE-6103
Project: HBase
Issue Type: Improvement
Reporter: Liyin Tang
Assignee: Liyin Tang
Currently HBaseServer is running with a single listener thread, which is
responsible for accepting the connection, reading the data from network
channel, deserializing the data into writable objects and handover to the IPC
handler threads.
So when there are multiple hbase clients connecting to the region server
(HBaseServer) and reading/writing a large set of data, this listener thread
will be performance bottleneck.
Ideally, the listener thread shall only accept the connection and handover the
connection to the IPC threads directly, so that each IPC thread would read the
data from network channel, deserialize the data and execute the Call.
In this way, the HBaseServer can read and deserialize data from each connection
in parallel.
