What is the purpose of BloomFilter in HBase?
In HBase, BloomFilter is a tool used to improve read performance. It is a data structure that quickly checks whether an element exists in a set. In HBase, BloomFilter is used to reduce unnecessary disk IO operations and improve read performance. It helps identify whether a row key exists in the corresponding HFile during read operations, avoiding disk IO operations on HFiles that do not contain the target row key, thus enhancing read performance. BloomFilter is optional in HBase and can be configured based on specific needs.
