> Performance Regression in Connection Initialization due to Configuration

> Key: PHOENIX-7464
> URL: https://issues.apache.org/jira/browse/PHOENIX-7464
> Project: Phoenix
> Issue Type: Bug
> Reporter: Lokesh Khurana
> Assignee: Lokesh Khurana
> Priority: Major
> Fix For: 5.3.0, 5.2.2
>
>
> 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.
