Carter Shanklin sent me some nice notes from working on a Python interface to the Phoenix QueryServer. He saw this strange thing in the code he had to write:
The value.value is strange. Looking at the protobuf definition, it seems like both ColumnValue and TypedValue are repeated which is causing this. Only one of them should be repeated, not both. This creates the equivalent of a 2dim array inside each row instead of just a 1dim array.
