> 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.
> [Here|https://docs.google.com/document/d/1ytwGDYGbEFuS3_eUEqRikh7wQABFyHjS0fXJ6wr1eSU/edit?usp=sharing] is the doc explaining the new APIs.
