      • authenticate

        public void authenticate​(AuthReq request,
                         io.grpc.stub.StreamObserver<AuthCtx> responseObserver)
        Log into a database to obtain an authentication context that can be used to execute SQL queries

      • sqlWithJsonResponse

        public io.grpc.stub.StreamObserver<SqlRequest> sqlWithJsonResponse​(io.grpc.stub.StreamObserver<SqlResponse> responseObserver)
        Executes the SQL query given and returns a JSON array response as a string.
The JSON array contains objects where each key is the name of the column, lowercased.
For example a table with the columns username, Age and CITY will return
[{"username":"Courtney","age":1,"city":"San Francisco"}]
i.e. the column names are lower cased, the values are the original as inserted into the table
If there are no results, the string returned will always be "[]"
i.e. you can always parse the string and assume there is a JSON array but it can be an empty array
