Kafka Streams is built on top of the Kafka producer/consumer API, and abstracts away some of the low-level complexities. In the context of the above example it looks like this: You use it in your Java applications to do stream processing. Kafka Streams a stream processing library, provided as part of Apache Kafka. enrichment (deriving values within a stream of a events, or joining out to another stream)Īs you mentioned, there are a large number of articles about this without wanting to give you yet another link to follow, I would recommend this one.aggregate (for example, the sum of a field over a period of time, or a count of events in a given window). Stream processing is used to do things like: This, in a rather crude nutshell, is stream processing. Maybe that stream we'll use for reporting, or driving another application that needs to respond to only red widgets events: We want to filter that stream based on a characteristic of the 'widget', and if it's red route it to another stream. Let's imagine we want to take this unbounded stream of events, perhaps its manufacturing events from a factory about 'widgets' being manufactured. An unbounded stream of events could be temperature readings from a sensor, network data from a router, order from an e-commerce system, and so on. Taking that unbounded stream of events, we often want to do something with it. Stream Processing is based on the fundamental concept of unbounded streams of events (in contrast to static sets of bounded data as we typically find in relational databases). What we want to achieve is to add artificial delay between window and sink operators to postpone sink emition. It is located in one region (with a read replica in a different region)īecause we are using event time characteristics with 1 minute tumbling window all regions' sink emit their records nearly at the same time.It is hosted in AWS via RDS (currently it is a PostgreSQL).The exact same code is running in each region.
