JDBC connection pool
Hi, everyone,
I'm new to drill.
I am running concurrent queries each holds its own JDBC connection to single drillbit node.
As I found, if one of the connections is closed, it will affect other connections and lead to unexpected channel close exception.
So does drill jdbc support connection pool?
How am I supposed to manage concurrent connections without interfering with each other?
Many thanks!
Iris

This is most likely a bug. I think it's similar to the following bug:
https://issues.apache.org/jira/browse/DRILL-3763
Please take a look at it and feel free to add more information to the
ticket.
Thanks
