Description

At present, Flink can use multiple sinks to write data into different data source such as HBase,Kafka,Elasticsearch,etc.And this process is concurrent ,in other words, one record will be written into data sources simultaneously.

But there is no approach that can sinking data serially.We really wish Flink can providing this kind of ability that a sink can write data into target database only after the previous sink transfers data successfully.And if the previous sink encounters any exception, the next sink will not work.
