Hi Folks:
A few newbie questions -
1. I wanted to find out what are the benefits of a queryable table
(https://calcite.apache.org/javadocAggregate/org/apache/calcite/schema/QueryableTable.html)
and what are the pros and cons of using it.
2. What is the role of Querable interface
(https://calcite.apache.org/javadocAggregate/org/apache/calcite/linq4j/Queryable.html)
?3. There is a getExpression methods in queryabletable
(https://calcite.apache.org/javadocAggregate/org/apache/calcite/linq4j/tree/Expression.html),
and I wanted to find out if it is required and what are the pros/cons of
implementing it.
4. What role does RawQueralbe play ?
(https://calcite.apache.org/javadocAggregate/org/apache/calcite/linq4j/RawQueryable.html).
It has a method getProvider method that returns QueryProvider. What roles
does query provider play ?5. What role does ExtendedQuerable play ?
Please let me know if there are any basic examples/blogs/documentation/etc.
Thanks for your help.
