What is stream processing in big data? Stream Processing is a Big data technology. It is used to query continuous data stream and detect conditions, quickly, within a small time period from the time of receiving the-data.

How is spark different from Hadoop? Hadoop is designed to handle batch processing efficiently whereas Spark is designed to handle real-time data efficiently. Hadoop is a high latency computing framework, which does not have an interactive mode whereas Spark is a low latency computing and canprocess data interactively.

What is Apache Spark core? Spark Core is the base of the whole project. It provides distributed task dispatching, scheduling, and basic I/O functionalities. Spark uses a specialized fundamental data structure known as RDD (Resilient Distributed Datasets)that is a logical collection of data partitioned across machines.

What is stream data processing? Stream processing is a-technology that let users query a continuous data stream and quickly detect conditions within a small time period from the time of receiving the data. It's one of the big data technologies that was popularized by Apache Storm.
