--------------------------------------------
Summary: Investigate latency of select roughly in columnar
warehouse
Key: LENS-310
URL: https://issues.apache.org/jira/browse/LENS-310
Project: Apache Lens
Issue Type: Sub-task
Components: driver-jdbc
Reporter: Amareshwari Sriramadasu
Assignee: Sushil Mohanty
Fix For: 2.1
We are using select roughly for doing explain on columnar warehouse.
This task is to investigate if select roughly can return in few milli seconds
latency.
Can the warehouse respond faster for select roughly even if it is running other
heavy queries?
If estimate is being called aggressively, do we want use same pool across both
execute and estimate in Lens? Shall we separate them for isolation?
