Samarth Jain commented on PHOENIX-971:
--------------------------------------
Out of curiosity [~ndimiduk] - how are you loading the PhoenixDriver?
PhoenixDriver right now is a singleton, so you would be having only one
HConnection per cluster unless you do what James suggested in the previous
comment.
bq - It seems a single process will share the underly ExecutorService across
all PhoenixDriver instances, even if multiple JDBC connections are used.
Is that the ExecutorService within HBase client or Phoenix?

> Host the JDBC driver in a query server process that can be deployed as a
> middle tier between lighter weight clients and Phoenix+HBase. This would
> serve a similar optional role in Phoenix deployments as the
> [HiveServer2|https://cwiki.apache.org/confluence/display/Hive/Setting+Up+HiveServer2]
> does in Hive deploys.
