Amazon Redshift will no longer support the creation of new Python UDFs starting November 1, 2025.
If you would like to use Python UDFs, create the UDFs prior to that date.
Existing Python UDFs will continue to function as normal. For more information, see the
blog post
SVL_SPECTRUM_SCAN_ERROR
You can query the system view SVL_SPECTRUM_SCAN_ERROR to get information about Redshift Spectrum scan errors.
SVL_SPECTRUM_SCAN_ERROR is visible to all users. Superusers can see all rows; regular users can see only their own data. For more information, see Visibility of data in system tables and views.
Some or all of the data in this table can also be found in the SYS monitoring view SYS_EXTERNAL_QUERY_ERROR. The data in the SYS monitoring view is formatted to be easier to use and understand. We recommend that you use the SYS monitoring view for your queries.
Table columns
Displays a sample of logged errors. The default is 10 entries per query.
| Column name | Data type | Description |
|---|---|---|
| userid | integer | The ID of the user that generated this row. |
| query | integer | The ID of the query that generated this row. |
| location | character(128) | The location of the data being queried. |
| rowid | character(128) | The location of the error within the file.
The rowid parts are separated with a : (colon) and additional parts might be added in the future.
A row_offset is the offset (in bytes) of the row within the file and is set to -1
for unsupported file formats.
A table is divided into row_groups, and each group has rows with distinct row_ids. |
| colname | character(128) | The name of the column returned by the query. |
| original_value | character(128) | Original value queried. |
| modified_value | character(128) | Modified value returned based on the data handling configuration option specified in the query. |
| trigger | character(128) | Data handling option specified in the query. |
| action | character(128) | Action associated with the data handling option specified in the query. |
| action_value | character(128) | Value of action parameter associated with the data handling option specified in the query. |
| error_code | integer | Result code of the data handling option specified in the query. |
Sample query
The following query returns the list of rows for which data handling operations were performed.
SELECT * FROM svl_spectrum_scan_error;
The query returns results similar to the following.
