It is similar to the spark but has some features enhanced. 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. Recently, Uber open sourced their latest Streaming analytics framework called AthenaX which is built on top of Flink engine. It processes only the data that is changed and hence it is faster than Spark. There are some continuous running processes (which we call as operators/tasks/bolts depending upon the framework) which run for ever and every record passes through these processes to get processed. One major advantage of Kafka Streams is that its processing is Exactly Once end to end. Before we get started with some historical context, you're probably wondering what in the world is .css-746vk2{transition-property:var(--chakra-transition-property-common);transition-duration:var(--chakra-transition-duration-fast);transition-timing-function:var(--chakra-transition-easing-ease-out);cursor:pointer;-webkit-text-decoration:none;text-decoration:none;outline:2px solid transparent;outline-offset:2px;color:var(--chakra-colors-primary-500);}.css-746vk2:hover,.css-746vk2[data-hover]{-webkit-text-decoration:none;text-decoration:none;color:var(--chakra-colors-primary-600);}.css-746vk2:focus-visible,.css-746vk2[data-focus-visible]{box-shadow:var(--chakra-shadows-outline);}Macrometa? But it will be at some cost of latency and it will not feel like a natural streaming. Flink also has high fault tolerance, so if any system fails to process will not be affected.
