---------------------------------------
Summary: Performance Regression in Connection Initialization due
to Configuration Handling in ConnInfo
Key: PHOENIX-7464
URL: https://issues.apache.org/jira/browse/PHOENIX-7464
Project: Phoenix
Issue Type: Bug
Reporter: Lokesh Khurana
The recent changes to {{ConnectionInfo}} (PHOENIX-6523) to resolve HBase
connection parameters earlier have introduced a performance regression
The root cause appears to be the heavy operation of creating an
{{HBaseConnection}} object. In contrast, Hadoop's implementation optimizes
configuration handling through efficient caching, making {{Configuration}}
object creation nearly cost-free.
Possible solutions include:
# Pre-loading and caching the default {{HBaseConfiguration}} object in
{{PhoenixDriver}} or {{{}ConnectionInfo{}}}.
# Investigating why HBase does not use a similar caching mechanism as Hadoop
and implementing improvements accordingly.
