Scenarios
Offline Data Analytics
After large volumes of logs on the servers of gaming platforms, web applications and mobile apps are synced to EMR data nodes or COS, tools such as Hue, Hive, Spark and Presto can help you quickly obtain deep insights into the data.
Other tools like Sqoop can then be used to load the data scattered across CDBs or other storage engines and sync the analyzed data to CDBs, providing data support for data visualization products such as RayData.
