13-
| [Vacuum Temp Files](/sql/sql-commands/administration-cmds/vacuum-temp-files) | Storage | - Free up storage by removing temporary files, notably join, aggregate, and sort spill files.<br/>- Set retention and file limits as needed. |
14-
| [Vacuum Dropped Table](/sql/sql-commands/ddl/table/vacuum-drop-table) | Storage | Optimizes storage by deleting data files of dropped tables. Offers a recovery option and a dry-run preview. |
15-
| [Vacuum Historical Data](/sql/sql-commands/ddl/table/vacuum-table) | Storage | Deep clean your storage space:<br/>- Remove orphan segment and block files. <br/>- Safely preview the removal of data files using the dry-run option. |
16-
| [Virtual Column](/sql/sql-commands/ddl/virtual-column) | Query | Enhance efficiency in querying Variant data:<br/>- Virtual columns streamline queries, eliminating the need to traverse the entire nested structure. Direct data retrieval accelerates query execution.<br/>- Virtual columns significantly cut memory usage in Variant data, reducing the risk of memory overflows. |
17-
| [Aggregating Index](/sql/sql-commands/ddl/aggregating-index) | Query | Elevate your query speed with aggregating indexes:<br/>- Supercharge queries through precomputed and indexed aggregations.<br/>- Customize the index to meet your unique data analysis requirements. |
18-
| [Computed Column](/sql/sql-commands/ddl/table/ddl-create-table#computed-columns) | Query | Computed columns save you time and effort by enabling derivation of new columns from existing ones:<br/>- Automatic updates ensure accurate and consistent data.<br/>- Advanced analysis and calculations can now be performed within the database.<br/>- Two types of computed columns: stored and virtual. Virtual columns save you space as they are calculated on-the-fly when queried. |
19-
| [Python UDF](/guides/query/udf#python-requires-databend-enterprise) | Query | A Python UDF allows you to invoke Python code from a SQL query via Databend's built-in handler, enabling seamless integration of Python logic within your SQL queries. |
20-
| [ATTACH TABLE](/sql/sql-commands/ddl/table/attach-table) | Query | Attach Table enables you to seamlessly connect a table in the cloud service platform to an existing table deployed in a private deployment environment without the need to physically move the data. |
21-
| [Stream](/sql/sql-commands/ddl/stream) | Data Streaming | Efficient data change management with stream:<br/>- Append-only mode supported: Instantly capture data insertions in real-time.<br/>- Seamlessly leverage streams for direct querying and analysis, ensuring swift insights. |
22-
| [Masking Policy](/sql/sql-commands/ddl/mask-policy/) | Security | Enhance your data security with role-based masking feature:<br/>- Safeguard sensitive information through customizable data masking.<br/>- Preserve data usability while reinforcing security. |
23-
| Storage Encryption | Security | Enhance the security of your server-side data encryption, safeguarding your data from unauthorized access by the storage vendor:<br/>- Choose encryption through service-managed keys, KMS managed keys, or customer-managed keys. Options may vary by storage type.<br/>- Currently supported on Alibaba Cloud OSS.<br/>See the [deploy guide](../../10-deploy/01-deploy/01-non-production/01-deploying-databend.md) for encryption parameters for each storage vendor. |
