Twitter Storm is an open source, big-data processing system intended for distributed, real-time streaming processing. R    This evolution required a technology capable of efficient computing of data distributed over several clusters. The processing is done while the data is in motion. A data stream management system (DSMS) is a computer software system to manage continuous data streams.It is similar to a database management system (DBMS), which is, however, designed for static data in conventional databases.A DSMS also offers a flexible query processing so that the information needed can be expressed using queries. Stream processing is still a niche application, even among big data users. A stream then models this data regardless of its type as a set of bytes and gives the application the ability to read or write into these bytes. Each data is generally timestamped and in some cases geo-tagged. The concept of dynamic steering involves dynamically changing the next steps or direction of an application through a continuous computational process using streaming. A data stream management system (DSMS) is a computer software system to manage continuous data streams.It is similar to a database management system (DBMS), which is, however, designed for static data in conventional databases.A DSMS also offers a flexible query processing so that the information needed can be expressed using queries. Also, these security technologies are inefficient to manage dynamic data and can control static data only. A sliding window may be like "last hour", or "last 24 hours", which is constantly shifting over time. If you are processing streaming data in real time, Flink is the better choice. For monitoring and detection of potential system failures. This made it difficult for existing data mining tools, technologies, methods, and techniques to be applied directly on big data streams due to the inherent dynamic characteristics of big data.
