-----------------------------
Status: Ready to Commit (was: Review In Progress)
> MapScan does not preserve top-level UDT values (returns empty map)
> -------------------------------------------------------------------
>
> Key: CASSGO-115
> URL: https://issues.apache.org/jira/browse/CASSGO-115
> Project: Apache Cassandra Go driver
> Issue Type: Bug
> Components: Core
> Reporter: Stanislav Bychkov
> Priority: Normal
> Fix For: 2.1.1
>
> Time Spent: 1h
> Remaining Estimate: 0h
>
> When reading rows that contain a top-level UDT column, MapScan() does not
> preserve the decoded UDT field values.
> 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{}
> h4. 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
> h4. 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
