ALECE: An Attention-based Learned Cardinality Estimator for SPJ Queries on Dynamic Workloads

Summary: ALECE uses attention to learn attribute-wise aggregations (data-encoder) and a query-analyzer that maps query features to these aggregations, capturing implicit correlations for SPJ queries on dynamic workloads. Plugged into PostgreSQL it yields near-optimal plans and outperforms existing estimators. (summarized by gpt-5-mini on Feb 09 2026)
