描述

Currently, global bloom index will check inputs against files in all partitions.. In lot of cases, the user may know a range of partitions actually impacted from updates clearly (e.g upstream system drops updates older than a year, ... ).. In such a scenario,it may make sense to support an option for Global bloom to control how many partitions you want to match against, to gain performance.

研究方向
Investigate GlobalBloomIndex implementation in the Hudi codebase (e.g., hudi client/hudi client common/src/main/java/org/apache/hudi/index/bloom/). Understand how partitions are currently considered and where a configuration option for limiting partitions could be added. Look for existing configuration parameters for BloomIndex. Discuss in the issue if maintainers have suggestions.
