Hello 👋 Where can we find Pinot server protobuf definitions files ? I'd like to try and connect to its gRPC streaming endpoint manually

Proto file is here: https://github.com/apache/pinot/blob/master/pinot-common/src/main/proto/server.proto Clients are here: https://github.com/apache/pinot/tree/master/pinot-common/src/main/java/org/apache/pinot/common/utils/grpc Also presto libs has already done the client side work as well: https://github.com/apache/pinot/tree/master/pinot-connectors/presto-pinot-driver/src/main/java/org/apache/pinot/connector/presto

Thank you @User :)

just a reminder, the inter broker server protocol change is considered as pinot internal, so it may change/upgrade with limit backward compatible support

Yes, got it I remember reading about versioning this interface to facilitate modifications with lesser impact on clients (e.g. Presto) - do I remember correctly ?

yes, versioning is there, just client side code needs to process higher version server response. You need to ensure client side upgrade before server or ping the dataTable version in server.
