generation
Timo Walther created FLINK-7403:
-----------------------------------
Summary: Remove expandLocalRef() before code generation
Key: FLINK-7403
URL: https://issues.apache.org/jira/browse/FLINK-7403
Project: Flink
Issue Type: Improvement
Components: Table API & SQL
Reporter: Timo Walther
Currently, we expand local references before code generation. This means that expressions that actually only need to be evaluated once, might be evaluated multiple times. We should remove the expand step where possible.
