Wenlong Lyu updated CALCITE-2492:
---------------------------------
Description:
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: {code} select * from
tableName with (start_time='', end_time='') {code}
