> The approach of substitution-based MV matching 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.
> Please check the design doc: [Design Doc|https://docs.google.com/document/d/1JpwGNFE3hw3yXb7W3-95-jXKClZC5UFPKbuhgYDuEu4/edit#]
