--------------------------------------
Summary: Make property names driver-agnostic for query
constraints, query selection policies and driver query hook
Key: LENS-1014
URL: https://issues.apache.org/jira/browse/LENS-1014
Project: Apache Lens
Issue Type: Wish
Reporter: Rajat Khandelwal
Right now, each driver has it's own specific property name for these things and
reading of these properties followed by initialization of objects based on
these is done in each driver.
Such code is mostly same for all the drivers. So with an Abstract class being
available to us, we can use that for removing code duplication. All code
mentioned in the previous paragraph can be moved to AbstractLensDriver.
Similarly, these property names can be unified.
The benefit will be that any new drivers getting added to Lens will already
have these functionalities without having to write code for these. The
functionality will be optional since AbstractLensDriver will default to null
objects. Plus, these will be available as standard features and property names
will be standard across drivers.
