Summary: SqlDialect supports pushing of all functions by default Key: CALCITE-2673 URL: https://issues.apache.org/jira/browse/CALCITE-2673 Project: Calcite Issue Type: Improvement Components: core Reporter: Jesus Camacho Rodriguez Assignee: Jesus Camacho Rodriguez Fix For: 1.18.0 SqlDialect contains a 'supportsFunction' that can be used by rules to know whether a certain function is supported in the given dialect, e.g., to choose whether to push a Filter expression to JDBC, etc. The default implementation of 'supportsFunction' always returns true. I believe a better idea would be to support in the default implementation for the method the most common SQL functions. Then each dialect can override that behavior and expand/limit the supported functions, e.g., JethroDataDialect already does that. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
