Real Time Data Streaming Processing Cheatsheet

This cheatsheet is a reference sheet for anyone who is getting started with real time data streaming processing. It covers the concepts, topics and categories related to real time data streaming processing, time series databases, spark, beam, kafka, and flink.

Real Time Data Streaming Processing

Real time data streaming processing is the process of processing data in real time as it is generated. This is different from batch processing, where data is processed in batches after it has been generated. Real time data streaming processing is used in a variety of applications, including financial trading, social media, and IoT.

Key Concepts

Data Stream: A continuous flow of data that is generated in real time.
Data Processing: The process of analyzing and transforming data in real time.
Real Time: The ability to process data as it is generated, without delay.
Batch Processing: The process of processing data in batches after it has been generated.
Event Time: The time at which an event occurred, as opposed to the time at which it was processed.
Processing Time: The time at which an event is processed, as opposed to the time at which it occurred.
