Why I'm doing:

image
Cached fragment(Fragment 0) should not use exogenous runtime filters produced by remote fragment(Fragment 2's HashJoin(2) ), since the HashJoin(2)'s runtime filter changes as its the right side changes. so we should disable query cache in this situation.

When we take this into conderation , we use PlanFragment.get{Build,Probe}RuntimeFilters methods to obtain fragment-specific runtime filter informations that are not be collected before using.

What I'm doing:

Collection runtime filter build/probe information in PlanFragmentBuilder

+        fragments.forEach(PlanFragment::collectBuildRuntimeFilters);
+        fragments.forEach(PlanFragment::collectProbeRuntimeFilters);
