+##Usage scenarios
+
+ A typical scenario is that the data is cleaned and preprocessed by Flink,
and then written to Carbon,
+ for subsequent analysis and queries.
+
+ The CarbonData flink integration module is used connect Flink and Carbon in
the above scenario.
+
+ The CarbonData flink integration module provides a set of Flink BulkWriter
implementations
+ (CarbonLocalWriter and CarbonS3Writer). The data is processed by the Flink,
and finally written into
+ the stage directory of the target table by the CarbonXXXWriter.
+
+ By default, those data in table stage directory, can not be immediately
queried, those data can be queried
+ after the "INSERT INTO $tableName STAGE" command is executed.
