> Key: PHOENIX-5812
> URL: https://issues.apache.org/jira/browse/PHOENIX-5812
> Project: Phoenix
> Issue Type: Improvement
> Reporter: Daniel Wong
> Priority: Major
> Labels: quality-improvement
>
> As Phoenix may keep a maximum default number of connections. Badly performing client calls or internal errors (See PHOENIX-5802). Can cause total available connections to go to 0. Proposing a client connection monitor with a connection reaper like task to reap idle connections.
> Definition of "Idle"
> Simple may be simple time based say if a connection has been open for configurable amount of minutes simply close.
> More complicated solution may be keeping track of last interaction time.
