---------------------------------
Summary: Stream Join
Key: CALCITE-4125
URL: https://issues.apache.org/jira/browse/CALCITE-4125
Project: Calcite
Issue Type: Sub-task
Reporter: Rui Wang
Right now stream JOIN is supported in syntax (e.g. in planner), however, there
are more areas needs a enhancement:
1. Does windowing strategy in JOIN have a constraint? For example, is a TUMBLE
stream allowed to join a HOP stream?
2. If there is any constraints on windowing strategy in JOIN, how will that
affect JOIN ordering?
3. How to optimize stream join stream or stream join table, which, by nature,
should be different from table join table?
