Amazon Redshift will no longer support the use of Python UDFs after June 30, 2026.
We will start enforcing it in phases. For more information on the details of Python end of life

Describe a table
To get metadata that describes a table, use the aws redshift-data
describe-table Amazon CLI command.
The following Amazon CLI command runs a SQL statement against a cluster and returns metadata that describes a table. This example uses the Amazon Secrets Manager authentication method.
aws redshift-data describe-table --cluster-identifier mycluster-test --database dev --schema information_schema --table sql_features --secret-arn arn:aws:secretsmanager:us-west-2:123456789012:secret:myuser-secret-hKgPWn
The following is an example of the response.
{ "ColumnList": [ { "isCaseSensitive": false, "isCurrency": false, "isSigned": false, "length": 2147483647, "name": "feature_id", "nullable": 1, "precision": 2147483647, "scale": 0, "schemaName": "information_schema", "tableName": "sql_features", "typeName": "character_data" }, { "isCaseSensitive": false, "isCurrency": false, "isSigned": false, "length": 2147483647, "name": "feature_name", "nullable": 1, "precision": 2147483647, "scale": 0, "schemaName": "information_schema", "tableName": "sql_features", "typeName": "character_data" } ] }
The following Amazon CLI command runs a SQL statement against a cluster that describes a table. This example uses the temporary credentials authentication method.
aws redshift-data describe-table --db-user myuser --cluster-identifier mycluster-test --database dev --schema information_schema --table sql_features
