Outsourcing adds more value to your business as it helps you reach your business goals and objectives. I am not sure if it supports exactly once now like Kafka Streams after Kafka 0.11, Lack of advanced streaming features like Watermarks, Sessions, triggers, etc. Although it is compared with different functionalities of Hadoop and MapReduce models, it is actually a parallel platform for stream data processing with improved features. It checkpoints the data source, sink, and application state (both windows state and user-defined state) in regular intervals, which are used for failure recovery. Fault tolerance comes for free as it is essentially a batch and throughput is also high as processing and checkpointing will be done in one shot for group of records. Flink is a fourth-generation data processing framework and is one of the more well-known Apache projects. While Storm, Kafka Streams and Samza look now useful for simpler use cases, the real competition is clear between the heavyweights with latest features: Spark vs Flink, When we talk about comparison, we generally tend to ask: Show me the numbers :). Scalability, where throughput rates of even one million 100 byte messages per second per node can be achieved. Of course, you get the option to donate to support the project, but that is up to you if you really like it. It is also used in the following types of requirements: It can be seen that Apache Flink can be used in almost every scenario of big data. Hence, one can resolve all these Hadoop limitations by using other big data technologies like Apache Spark and Flink. Thus, Flink streaming is better than Apache Spark Streaming. Technically this means our Big Data Processing world is going to be more complex and more challenging. For example, there could be more integration with other big data vendors and platforms similar in scope to how Apache Flink works with Cloudera. Disadvantages of Online Learning.
