             Summary: is there any way to define dynamic parameters for table in query
                 Key: CALCITE-2492
                 URL: https://issues.apache.org/jira/browse/CALCITE-2492
             Project: Calcite
          Issue Type: New Feature
            Reporter: Wenlong Lyu
            Assignee: Julian Hyde


Currently we are trying to implement a catalog and sql engine with calcite, which need to support define table representing all kinds of storage: message queue, db, etc. When try to query a table of message queue from catalog, we need to specify the range of data to scan，such like start_time/end_time, which is not supported in calcite。
Is there a good way to solve a problem?
Is it good to extend calcite with dynamic parameters like: {{ select * from tableName with (start_time='', end_time='') }}
