[jira] [Updated] (CALCITE-3334) Refinement for Substitution-Based MV Matching

     [ https://issues.apache.org/jira/browse/CALCITE-3334?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

jin xing updated CALCITE-3334:
------------------------------
    Description: 
The approach of substitution is an effective way for its simplicity and extensibility. 

This JIRA proposes to refine existing implementation by several points:
 # Canonicalize before MV matching -- by such canonicalization we can significantly simplify the algebra tree and lower the difficulty for materialization matching.
 # Separate matching rules into two categories and enumerate common matching patterns which need to be covered by rules.
