This is a group for anyone interested in Big Data Streaming development, research, usage and promotion. We start this group to meet the big data streaming developers and users in China and to promote the big data streaming usage. In this group, any topic about big data streaming (e.g. deployment/administration, new uusage model, etc.) is welcome. All big data streaming frameworks, e.g. (but not limited to) Apache Storm/JStorm, Gearpump, Apache Spark Streaming, Apache Flink, Apache MXNET, Petuum etc. will be discussed.
