-------------------------------------
Summary: [FlightRPC] Add a "Flight SQL" extension on top of
FlightRPC
Key: ARROW-9825
URL: https://issues.apache.org/jira/browse/ARROW-9825
Project: Apache Arrow
Issue Type: New Feature
Components: FlightRPC, Format
Reporter: Ryan Nicholson
As a developer of database clients and backends, I would like to have a
standard in place to communicate between the two while being able to leverage
the data transfer features of Arrow Flight.
The Arrow Flight RPC specification allows for extensibility by using opaque
payloads to perform “Actions”, specify “Commands” and so on.
I propose the addition of a Flight SQL extension consisting of predefined
protobuf messages and workflows to enable features such as:
* Discovering specific database capabilities from generic clients
* Browsing catalogs.
* Execution of different types of SQL commands.
Supporting documentation and a POC changelist will be sent to the mailing list
in the coming days which describes protobuf messages and workflows enabling
these features.
