A BiLSTM cardinality estimator in complex database systems based on attention mechanism
Abstract An excellent cardinality estimation can make the query optimiser produce a good execution plan. Although there are some studies on cardinality estimation, the prediction results of existing cardinality estimators are inaccurate and the query efficiency cannot be guaranteed as well. In parti...
