What is the role of a RegionServer in HBase?
RegionServer in HBase is a component of the HBase cluster responsible for managing regions within HBase. Each RegionServer is in charge of managing a certain number of regions, each of which contains a certain number of HFiles. RegionServer handles client requests, reads and writes data, as well as tasks such as data sharding and load balancing. RegionServer periodically flushes data from memory to disk to ensure data persistence. In HBase, RegionServer is a working node in the cluster responsible for storing and managing data operations.
