Which of the following scenarios are not good for Flink components? (Multiple choice)

Batch processing

Iterative calculation

Stream processing

Data storage

QUESTION 264
The MOB data in HBase is directly stored in HFile format on HDFS, and then the address information and size information of this file are stored as value on the store that manages HBase, and these files are managed centrally through tools.
