Architecting an on-premises enterprise database with AI capabilities requires a clear separation of concerns. The database serves as the secure system of record and metadata store, while vector retrieval, document storage, and orchestration are handled by specialized, integrated components. This layered approach ensures performance, security, and data sovereignty within the private cloud or data center.<\/p>\n
Before implementing vector storage or hybrid retrieval, verify the following prerequisites.<\/p>\n
A robust on-premises AI architecture separates the transactional system of record from the vector retrieval layer. KingbaseES provides a multi-model architecture that supports Relational, Document, Spatial, Time Series, Text Data, Vector embeddings, Key-Value, and Property Graph\/RDF within a single system. This eliminates the need for multiple specialized databases for different data models.<\/p>\n
However, the database acts as the secure foundation for metadata and embeddings. The actual AI inference and vector similarity search logic often require integration with external vector engines or specialized libraries. This distinction prevents the misconception that the RDBMS alone handles all AI tasks.<\/p>\n
The architecture typically follows this flow:<\/p>\n
This separation ensures that sensitive data remains within the corporate firewall while allowing flexibility in choosing the best tools for vector indexing and inference.<\/p>\n
KingbaseES supports Vector embeddings as a data model within its multi-model architecture. The following steps outline the general procedure for creating tables to store vector data. Note that specific indexing commands and query syntax for vector similarity search must be verified against the vendor documentation for the specific version in use.<\/p>\n
Define a table structure that includes standard columns for metadata and a column for the vector embeddings. Consult the KingbaseES documentation for the exact syntax to define vector columns.<\/p>\n
Insert data into the table, ensuring the vector dimension matches the embedding model used (e.g., 768, 1024, or 1536 dimensions). Use the appropriate data insertion methods supported by your KingbaseES version.<\/p>\n
Create standard indexes on metadata columns to support efficient hybrid retrieval. Vector indexing requires specific commands that are version-dependent. Consult the vendor documentation for the correct syntax to create vector indexes.<\/p>\n
Query the table to ensure vectors are stored correctly and metadata is accessible. Use standard SQL queries to verify data integrity.<\/p>\n
Security is paramount in on-premises AI deployments. KingbaseES supports various identity authentication methods, including national cryptographic (\u56fd\u5bc6) authentication, to meet strict security standards. This ensures that access to sensitive vector data and metadata is tightly controlled.<\/p>\n
Enable national cryptographic authentication in the configuration file (typically Use metadata columns to enforce row-level security or application-level access control. This ensures that users only access vector data relevant to their permissions.<\/p>\n Verifying the performance of vector queries is critical to ensure low-latency inference. Since vendor-specific latency benchmarks are not provided, perform local performance tests in your environment.<\/p>\n Verify that the vector column is correctly defined and indexed. Use the KingbaseES database object inspection platform to verify table structures.<\/p>\n Run queries that combine metadata filtering with vector retrieval to measure latency. Use standard SQL execution plans to analyze query performance.<\/p>\n Use database monitoring tools or client-side timing to measure the execution time of vector queries. Compare these metrics against your application’s latency requirements.<\/p>\n Ensure that the vector similarity search returns relevant results by comparing them with keyword search results.<\/p>\n Common failures in hybrid retrieval setups include mismatched embedding dimensions, metadata filter syntax errors, and integration issues with local LLMs.<\/p>\n Ensure the vector dimension in the database matches the output dimension of the embedding model. A mismatch will cause insertion errors or incorrect similarity calculations.<\/p>\n Verify the syntax of metadata filters. Use standard JSON operators for querying metadata in KingbaseES.<\/p>\n Check network connectivity and API endpoints between the database and the LLM service. Use the KingbaseES database object inspection platform to audit database objects and identify potential performance bottlenecks.<\/p>\n If AI extensions cause performance degradation or data inconsistency, follow these steps to rollback changes safely.<\/p>\n Identify the specific extensions or configuration changes causing issues. Use the KingbaseES database object inspection platform to audit recent changes.<\/p>\n Disable the AI-specific extensions or revert configuration changes. This may involve modifying Restart the KingbaseES service to apply the rollback changes.<\/p>\n Run integrity checks to ensure no data loss or corruption occurred during the rollback. Revert schema changes using standard database management practices.<\/p>\n Monitor database performance to ensure that core transactional stability is restored.<\/p>\n Verify the KingbaseES version supports Vector embeddings as a multi-model data type. Check the vendor documentation for specific version requirements and OS compatibility.<\/p>\n Consult the vendor documentation for supported embedding model types and integration methods. Perform local performance tests to validate hybrid retrieval performance.<\/p>\n Check for mismatched embedding dimensions and metadata filter syntax errors. Use the KingbaseES database object inspection platform to audit database objects. Rollback by disabling extensions and restarting the service, then verify data integrity using standard database management practices.<\/p>\n Keep all data processing within the corporate firewall. Use KingbaseES\u2019s national cryptographic authentication and metadata filtering to enforce strict access control. Ensure no sensitive data leaves the private infrastructure during AI inference.<\/p>\n \ud83d\udca1 More Resources<\/strong><\/p>\n If you would like to dive deeper into KingbaseES and its application practices across various industries, we have compiled the following official resources to help you get started quickly and develop and operate with efficiency:<\/p>\n Open Source Resources:<\/strong><\/p>\n Welcome to explore the resources above and begin your Kingbase journey!<\/p>\n","protected":false},"excerpt":{"rendered":" Prerequisites: Defining the On-Premises AI Architecture Boundaries Architecting an on-premises enterprise database with AI capabilities requires a clear separation of concerns.
