I'm almost done writing the implementation of this. It turned out to be a fairly complicated ordeal to compress/denormalize the flattened data from Flight SQL to ADBC's nested lists of structs. A couple of things: - I'm assuming we should _not_ use SqlQuirks to map Arrow types to type names for Flight SQL, since Flight SQL is already Arrow-designed and this should probably have happened in the Flight SQL Producer already. - If the user uses Depth ALL to get column metadata, and supplies a column pattern that filters out all columns, I am assuming the result should be that the table is still listed but the columns list is non-null but empty (as opposed to the table being filtered out entirely or the table being listed but the columns list being null). -- This is an automated message from the Apache Git Service.
