    @colindean I know Matt responded right after I did before, what are your 
thoughts on working on enabling unit tests by exposing the idle/active 
connection counts?


> DBCPConnectionPool configuration should expose underlying connection idle and 
> eviction configuration

>             Project: Apache NiFi
>          Issue Type: Improvement
>          Components: Extensions
>    Affects Versions: 1.8.0

> While investigating a fix for NIFI-5789, I noticed in the [DBCPConnectionPool 
> documentation|https://nifi.apache.org/docs/nifi-docs/components/org.apache.nifi/nifi-dbcp-service-nar/1.8.0/org.apache.nifi.dbcp.DBCPConnectionPool/index.html]
>  that NiFi appears _not_ to have controller service configuration options 
> associated with [Apache 
> Commons-DBCP|https://commons.apache.org/proper/commons-dbcp/configuration.html]
>  {{BasicDataSource}} parameters like {{minIdle}} and {{maxIdle}}, which I 
> think should be both set to 0 in my particular use case. 
> Alternatively, I think I could set {{maxConnLifetimeMillis}} to something 
> even in the minutes range and satisfy my use case (a connection need not be 
> released _immediately_ but within a reasonable period of time), but this 
> option is also not available.
