---------------------------------------
Summary: Track scan cardinality with Runtime Filters
Key: IMPALA-15063
URL: https://issues.apache.org/jira/browse/IMPALA-15063
Project: IMPALA
Issue Type: Improvement
Components: Backend, Frontend
Reporter: Quanlong Huang
Assignee: Quanlong Huang
In the initial work of HBO, scan cardinalities are ignored if some rows are
filtered out by runtime filters (RFs) since the cardinalities is
non-deterministic depending on whether the runtime filters arrive in time.
We can consider adding the RFs into the HBO key string so such scan
cardinalities can be reused in estimation when applying the same set of RFs.
