-----------------------------------------
Summary: Codegen Tuple size in Sorter
Key: IMPALA-11474
URL: https://issues.apache.org/jira/browse/IMPALA-11474
Project: IMPALA
Issue Type: Improvement
Components: Backend
Reporter: Noemi Pap-Takacs
The sorter works with fixed-length tuples. The number of bytes in a tuple is
known before execution, it is available in the query plan. However, currently
the tuple size is treated as a member variable in the TupleSorter. Using
Codegen to replace this member variable by a constant in sorter-ir.cc could
speed up the quicksort phase.
