Subject [jira] [Commented] (NIFI-6684) Add more property to Hive3ConnectionPool
Date Sun, 22 Sep 2019 12:09:00 GMT


Alessandro D'Armiento commented on NIFI-6684:

Hello [~jamescheng], I took a look on the two processors. 
Some of the features you ask are definetely possible, however, unfortunately you are comparing
two processors which relies on different versions of commons-dbcp (that is, Hive3ConnectionPool
uses an older implementation). 

For this reason, in a minor update MAX_CONN_LIFETIME and SOFT_MIN_EVICTABLE_IDLE_TIME could
not be added. I am however working on introducing MIN_IDLE,  MAX_IDLE, EVICTION_RUN_PERIOD

> The Hive3ConnectionPool is similar with DBCPConnectionPool as both of them are using DBCP
BasicDataSource. However, Hive3ConnectionPool  doesn't provide some properties of what DBCPConnectionPool 
has. Such as "Minimum Idle Connections", "Max Idle Connections", "Max Connection Lifetime",
"Time Between Eviction Runs", "Minimum Evictable Idle Time" and "Soft Minimum Evictable Idle
> This improvement is try to provide more properties for developer to set.
