|--------------|--------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------|
302-
| `s3.crt.target-throughput-gbps` | 10.0 | Target throughput in Gbps for the S3 CRT (Common Runtime) client. This setting helps optimize performance when creating the S3 CRT client. |
303-
| `s3.crt.max-concurrency` | - | Maximum number of concurrent requests for the S3 CRT client. Used to control the level of parallelism in S3 operations. |
304-
| `s3.crt.max-native-memory-limit-bytes` | - | Maximum native memory limit in bytes for the S3 CRT client. Helps manage memory usage of the client. |
305-
| `s3.crt.multipart.threshold-bytes` | - | Threshold in bytes for switching to multipart uploads in the S3 CRT client. Files larger than this size will use multipart uploads. |
306-
| `s3.transfer-manager-provider` | <code>com.arcesium.swiftlake.aws.<br>SingletonS3TransferManagerProvider</code> | Specifies the class name for the S3 transfer manager provider. This class is responsible for creating and managing S3TransferManager instances. |
307-
| `s3.transfer-manager-provider.*` | - | Prefix for additional properties specific to the configured S3 transfer manager provider. These properties are passed to the provider during initialization. |
308-
| `s3.duckdb.s3-extension-enabled` | false | Enables or disables the DuckDB S3 extension integration. When true, allows for direct querying of S3 data using DuckDB. |
309-
| `s3.duckdb.s3-extension-threshold-bytes` | - | Minimum file size (in bytes) for using DuckDB S3 integration. If the file size is greater than or equal to this value, DuckDB S3 integration is used. |
