Hello, I just want to ask if the ScanType in the avatica-go driver could be removed. I don't find any references for it (its set, but never read) and I'm facing errors when requesting columns with a non-trivial data type.
Unfortunately it even panics when it column metadata which doesn't contain a well known type (INT, VARCHAR etc...) In the [generic adapter]( https://github.com/apache/calcite-avatica-go/blob/master/generic/generic.go#L38) is a method which prepares the ColumnMetaData for further use and also sets up the ScanType values by switching over the reported data type for each column. If there is any non-standard data type specified, the default case is used, which results in a panic. While investigating this I found out that the ScanType is never used in the driver for actually scanning the data. I assume that this is some old code which could be removed, but I'm not totally sure. Could someone of you check if that whole ScanType logic can be removed? If yes I'm more that happy to create a PR for this. With kind regards, Tino
