Summary: Split AbstractMaterializedViewRule into multiple classes
Key: CALCITE-3825
URL: https://issues.apache.org/jira/browse/CALCITE-3825
Project: Calcite
Issue Type: Improvement
Components: core
Reporter: Jesus Camacho Rodriguez
Assignee: Jesus Camacho Rodriguez
AbstractMaterializedViewRule contains a materialized view-based rewriting
algorithm that has been there for multiple releases and it is used by some
engines relying in Calcite, e.g., Apache Hive.
The main reason to have a single file/class for the rule was to make the logic
self-contained instead of spreading it between multiple files from the onset,
as it was experimental and we were not sure how far the implementation would
go. In retrospective, we should have refactor that code sooner rather than
later, since it makes very difficult to understand and maintain logic that is
already complicated enough.
This issue is to split AbstractMaterializedViewRule into multiple files/classes
(it already contained multiple internal classes).
