- 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.
