Target customers: all users. Features released: EMR provides DataServing clusters, which are more flexible, reliable, and efficient than other types of clusters. DataServing clusters provide the HBase service and are separated from data storage based on OSS-HDFS. In addition, data is cached by using JindoData to improve the read and write performance of DataServing clusters. Benefits of DataServing clusters: 1. OSS-HDFS is used as the storage to separate computing clusters from storage systems.This reduces the costs of clusters. You can create an HBase cluster based on data stored in OSS-HDFS. 2. Node groups of clusters can be scaled. You can scale in a node group by decommissioning the nodes in the node group. 3. Phoenix is supported. This allows you to easily use HBase. 4. More metrics are monitored and inspected.
