Quarkus gRPC: Option to set max message size

[shashankbrgowda]

I'm getting an error when I try to return below message (Uni< FetchAllSliceResponse>). I can't return stream because I need to collect the stream and perform some business logic.

message FetchAllSliceResponse {
  repeated Slice slices = 1;
}
message Slice {
  CoordSystem coord_system = 1;
  int32 start = 2;
  int32 end = 3;
  int32 strand = 4;
  int32 seq_region_id = 5;
  string seq_region_name = 6;
  int32 seq_region_length = 7;
}
message CoordSystem {
  string name = 1;
  string version = 2;
  int32 rank = 3;
  int32 top_level = 4;
  int32 sequence_level = 5;
  int32 default = 6;
  int32 db_id = 7;
  string alias_to = 8;
}

{
  "error": "8 RESOURCE_EXHAUSTED: Received message larger than max (6597151 vs. 4194304)"
}

Is there any option to set max gRPC message size on server side ?
