Hello,
Ryan Murray has proposed adding a GetFlightSchema RPC [1] to the Arrow
Flight Protocol [2]. The purpose of this RPC is to allow decoupling schema
and endpoint retrieval as provided by the GetFlightInfo RPC. The new
definition provided is:
message SchemaResult {
// Serialized Flatbuffer Schema message.
bytes schema = 1;
}
rpc GetSchema(FlightDescriptor) returns (SchemaResult) {}
Ryan has also provided a PR demonstrating implementation of the new RPC [3]
in Java, C++ and Python which can be reviewed and merged after this
addition is approved.
Please vote whether to accept the addition. The vote will be open for at
least 72 hours.
[ ] +1 Accept this addition to the Flight protocol
[ ] +0
[ ] -1 Do not accept the changes because...
Thanks,
Micah
