- Obtaining available materialized view adjustments after partition pruning RBO rewrite rules. This reduces partition version comparison overhead for partitioned materializations, thereby improving performance. - Set maximum time threshold for transparent query rewriting with default value of 1000ms. Rewrite attempts will be terminated if exceeding this threshold. set materialized_view_rewrite_duration_threshold_ms = 1000 - Optimize code structure in transparent rewriting framework: 1. Replace Lambda expressions with conventional for-loops 2. Remove redundant member variables - Cache available partitions of materialized views. Since calculating available partitions for materialized views is time-consuming, caching can significantly enhance performance. Co-authored-by: zhangdong <zhangdong@selectdb.com>
