[jira] [Created] (IMPALA-14846) HBO for computing KuduScanNode and HBaseScanNode cardinality

Quanlong Huang created IMPALA-14846:
---------------------------------------

             Summary: HBO for computing KuduScanNode and HBaseScanNode cardinality
                 Key: IMPALA-14846
                 URL: https://issues.apache.org/jira/browse/IMPALA-14846
             Project: IMPALA
          Issue Type: New Feature
          Components: Frontend
            Reporter: Quanlong Huang


Kudu tables and HBase tables can have realtime ingestion and Impala is not aware of the changes, e.g., catalog version in Impala remains unchanged. The HBO key strings of them need more fields, e.g., timestamp, to better match a historical run.
