Phoenix Connector: Configure Page size while creating Connection

[virajjasani]

Description

Phoenix provides a way to configure Page size while creating JDBC Connection. Page size in Phoenix is important aspect to control how much work a single HBase RPC handler should perform before timing out. When the given RPC thread times out based on the page size, Phoenix client retrieves dummy result from the server and resume the operation by sending another RPC request, until eventually the result iteration is completed.

As Phoenix supports both OLTP and OLAP workloads, setting the page size timeout is crucial to manage HBase server resources efficiently. While by default, Phoenix client relies on HBase RPC timeout values to derive Page size, using Configuration property is flexible and efficient way for the clients to have better control.
