Abstract
A database system that, after receiving the query request, adopts a pre-trained deep learning model to predict probing cardinality corresponding to the query request based on the query vector in the query request, the number of vectors of the query result, and the vector corresponding to the distances between the query vector and the center vector of a plurality of data partitions stored in the storage device. The system then determines the target data partitions according to the probing cardinality, and obtains the query result from the target data partitions. Since the probing cardinality is dynamically determined based on the query request, decreases to both the query efficiency due to a larger setting of the probing cardinality, and the query recall due to a smaller setting of the probing cardinality are avoided, which is beneficial in reducing the average number of target data partitions and improving query efficiency.
