ribaraka opened a new issue, #1938:
URL: https://github.com/apache/cassandra-gocql-driver/issues/1938
When reading rows that contain a top-level UDT column,
`MapScan(map[string]interface{})` does not preserve the decoded UDT field
values, while `Scan(&map[string]interface{})` works as expected.
For a top-level `frozen<udt>` column:
- Scan(...) can decode the UDT correctly
- MapScan(...) returns the row, but the UDT value is an empty
map[string]interface{}
### Expected behavior
MapScan should preserve top-level UDT contents consistently with Scan
A non-null UDT column should decode into a populated map[string]interface{}
containing its field values
### This is particularly problematic because:
- The column itself is present
- No error is raised
- The data is silently lost rather than missing or failing loudly
