It can be simply understood as a indexing and retrieval tool. Of course, it has more functions than this.ElasticSearch cons

Use Akka to optimize quasi-real-time systems of Spark + ElasticSearch In this scenario, the system receives a large number of events every second. Each event contains many parameters, in addition to quasi-real-time data, you must periodically determine whether the combination of each event and event parameter value has exceeded the threshold value set by the system. In this scenario, what kind of solutions should users adopt? Recently, Android Camilo,
