Daniel Wong commented on PHOENIX-5812:
--------------------------------------
Thoughts [~liuml07]? [~vmeka]
I think the requirements would look like this:
* New Connection Level Property phoenix.connection.lifetime or similar
* defaults to 0, for infinity ie do not close connections.
* When non-0, connections that are open longer than
phoenix.connection.lifetime are closed. (Could be CQS or elsewhere).
* New global metric for number of reaped connections counter. Individual
users can metric/alarm on this.
> Automatically Close "Idle" Long Open Connections

> Key: PHOENIX-5812
> URL: https://issues.apache.org/jira/browse/PHOENIX-5812
> Project: Phoenix
> Issue Type: Improvement
> Reporter: Daniel Wong
> Priority: Major
>
> 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.
