--------------------------------------
Summary: Rel Id generator should not be static
Key: CALCITE-3879
URL: https://issues.apache.org/jira/browse/CALCITE-3879
Project: Calcite
Issue Type: Improvement
Components: core
Reporter: Haisheng Yuan
The rel id will continue increasing until the class is unloaded. We have
observed that the id is reaching 100 million after running for just several
days. Although we don't use the id for calculation, it might be OK for integer
overflow, but it doesn't make sense to generate unique id globally, it will
hard to read the dumped plan and the rel id in the log, because the rel id is
so large. IMO, the id should be generated per query context.
