Enterprise Feature List

FeatureCategoryDescription
Vacuum Temp FilesStorage- Free up storage by removing temporary files, notably join, aggregate, and sort spill files.
- Set retention and file limits as needed.
Vacuum Dropped TableStorageOptimizes storage by deleting data files of dropped tables. Offers a recovery option and a dry-run preview.
Vacuum Historical DataStorageDeep clean your storage space:
- Remove orphan segment and block files.
- Safely preview the removal of data files using the dry-run option.
Virtual ColumnQueryEnhance efficiency in querying Variant data:
- Virtual columns streamline queries, eliminating the need to traverse the entire nested structure. Direct data retrieval accelerates query execution.
- Virtual columns significantly cut memory usage in Variant data, reducing the risk of memory overflows.
Aggregating IndexQueryElevate your query speed with aggregating indexes:
- Supercharge queries through precomputed and indexed aggregations.
- Customize the index to meet your unique data analysis requirements.
Computed ColumnQueryComputed columns save you time and effort by enabling derivation of new columns from existing ones:
- Automatic updates ensure accurate and consistent data.
- Advanced analysis and calculations can now be performed within the database.
- Two types of computed columns: stored and virtual. Virtual columns save you space as they are calculated on-the-fly when queried.
Python UDFQueryA 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.
ATTACH TABLEQueryAttach 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.
StreamData StreamingEfficient data change management with stream:
- Append-only mode supported: Instantly capture data insertions in real-time.
- Seamlessly leverage streams for direct querying and analysis, ensuring swift insights.
Masking PolicySecurityEnhance your data security with role-based masking feature:
- Safeguard sensitive information through customizable data masking.
- Preserve data usability while reinforcing security.
Storage EncryptionSecurityEnhance the security of your server-side data encryption, safeguarding your data from unauthorized access by the storage vendor:
- Choose encryption through service-managed keys, KMS managed keys, or customer-managed keys. Options may vary by storage type.
- Currently supported on Alibaba Cloud OSS.
See the deploy guide for encryption parameters for each storage vendor.
