--------------------------------------

             Summary: Add metadata and prepared statement APIs to DrillClient<->Drillbit
interface
                 Key: DRILL-4714
                 URL: https://issues.apache.org/jira/browse/DRILL-4714
             Project: Apache Drill
          Issue Type: New Feature
            Reporter: Venki Korukanti


Currently ODBC/JDBC drivers spawn a set of queries on INFORMATION_SCHEMA for metadata. Client
has to deal with submitting a query, reading query results and constructing required objects.
Sometimes same work is done twice (planning work in case of prepare statements) to get the
metadata and execute query. Instead we could simplify the client by providing APIs on the
client interface and let the server construct the required objects and send them to client
directly. These APIs provide common info that can be consumed by the JDBC/ODBC driver.

Will attach a doc explaining the new APIs.
