Description

The default value for configuration parameter 'planner.width.max_per_node' is shown as 0 in Drill 1.12. In the previous versions, the default value is set as 70% total core in the drillbit node.This could be confusing for users upgrading from previous versions ( Whether it is unlimited value).
