> SegmentPruner add the checks for "OR" filtering
> -----------------------------------------------
>
> Key: KYLIN-4280
> URL: https://issues.apache.org/jira/browse/KYLIN-4280
> Project: Kylin
> Issue Type: Improvement
> Components: Query Engine
> Reporter: yangzhang
> Assignee: yangzhang
> Priority: Major
> Fix For: v2.6.5, v3.1.0
>
>
> The "SegmentPruner" can check whether a segment can be skipped or not by
> checking the min/max dimension value with the "where " conditions.
> While, the current "SegmentPruner" only checks the simple logic condition
> ("COL=X") or "AND" conditions. This means, if there is a "OR" condition,
> Kylin will not check the sub-conditions.
> This change is to add the support for checking sub-conditions under "OR".
