Overview

MRS is a big data cluster running based on the open-source Hadoop ecosystem. It provides the industry's latest cutting-edge storage and analytical capabilities of massive volumes of data, satisfying your data storage and processing requirements. For details, see the MapReduce Service User Guide.

You can use Hive/Spark (analysis cluster of MRS) to store massive volumes of service data. Hive/Spark data files are stored on HDFS. On GaussDB(DWS), you can connect a GaussDB(DWS) cluster to an MRS cluster, read data from HDFS files, and write the data to GaussDB(DWS) when the clusters are on the same network.
