AI Technical Summary
Existing technologies exhibit significant performance bottlenecks and data inconsistencies in big data BI scenarios, particularly when relying on external microservices, and lack rapid recovery capabilities.
By constructing a two-level cache that maps metadata to entity objects and execution plans, local cache queries are enabled, avoiding dependence on external services. Related entities are encapsulated into a single entity object for circulation, ensuring data consistency, and the cache is updated promptly when metadata changes.
It effectively avoids performance bottlenecks caused by external services, ensures data consistency, and supports the stability and scalability of data services through the rapid recovery capability of local caching.
