What is Kinesis Data Analytics?
Kinesis Data Analytics is a managed service from AWS for processing and analyzing streaming data in real-time.
It‘s part of the Kinesis family of services, which also includes Kinesis Data Streams, Kinesis Data Firehose, and Kinesis Video Streams.
The key idea behind Kinesis Data Analytics is it allows you to gain timely insights and quickly react to new data from continuous streams. This could be data flowing from IoT devices, web and mobile apps, DevOps logs, or hundreds of other sources.
Instead of having to manage your own Apache Flink or Apache Spark cluster, Kinesis Data Analytics provides a fully managed runtime environment out of the box.
All you have to do is supply the streaming data and write your analysis logic using simple SQL or Java code. The service handles all the underlying infrastructure, management, and scaling tasks behind the scenes.
This allows you to focus on analyzing data rather than building and babysitting a complex distributed system.
Now you may be wondering – how is this different than running Apache Flink or Spark on Amazon EMR?
Good question! While EMR provides the raw processing cluster, Kinesis Data Analytics adds critical capabilities like:
- Automatic scaling based on load
- Built-in high availability
- Tight integration with AWS data sources
- Managed checkpoints and state backend
