IMPALA-15175: Support HBO for AnalyticEvalNode cardinality
AnalyticEvalNode appends analytic results to the input tuples as new
columns. Though they won't change the cardinality, the analytic results
could be used in downstream group-by keys, join keys, or predicates,
which matters in cardinalities of downstream nodes. So we need to track
AnalyticEvalNodes in HBO.
The HBO key string of an AnalyticEvalNode consists of
- Analytic functions
- PartitionBy Exprs
- OrderBy Exprs
- Window
- The child's HBO key string
Exprs are canonicalized with operand indexes if the child node has
multiple output tuples, e.g., JoinNode. PartitionBy Exprs are sorted
since the order doesn't matter. OrderBy Exprs are added using the
original order.
Testing
- Added FE tests and e2e tests
Assisted-by: Opus 4.8 (Claude Code)
