Eugene Koifman commented on HIVE-16383:
---------------------------------------
All of these conn pool libs support reading their config from an xml file.
Wouldn't it be better to just 1 prop per pool to point at it's config file?
This way there is no explosion of props
> Switch to HikariCP as default connection pooling
