I have a dashboard application (using Zoomdata) in which we submit queries to a Impala resource pool with limited number of concurrent requests. While we load the dashboard, some queries might get queued if conc. requests limit is reached.
When I change the dashboard time range, I noticed the running queries are properly cancelled, but the queued ones stay in the queue and are going to execute before the new queries submitted.
Do you know if there is any Impala JDBC driver property or Impala server setting to be able to cancel queued queries and prevent them from running?
