Throughput: The amount of data processed in a given period of time Event Stream : A continuous flow of data events generated by various sources, such as sensors, user interactions, or transactions. Stream Processing : The real-time processing of data streams to extract insights and trigger actions. Data Ingestion : The process of collecting and importing data for immediate use or storage. Scalability : The capability of a system to handle growing amounts of work or data by adding resources. Fault Tolerance : The ability of a system to continue operating without interruption when one or more of its components fail.

Data is processed as soon as it is generated or received, enabling immediate insights and actions. Characteristics: • Latency: Very low, often in milliseconds or seconds. • Data Handling: Continuous flow of data, processed in real-time. • Use Cases: Fraud detection, real-time recommendations, live monitoring, financial trading. • Technologies: Apache Kafka, Apache Storm, Apache Flink, Spark Streaming.
- 5. Click to edit Master title style 5 5 Batch Processing Batch processing involves collecting data over a period and processing it in bulk. Data is accumulated, then processed at scheduled intervals, allowing for comprehensive analysis of large data sets. Characteristics: • Latency: Higher, ranging from minutes to hours or even days. • Data Handling: Processes data in large volumes at specific intervals. • Use Cases: End-of-day reporting, data warehousing, historical data analysis. • Technologies: Hadoop MapReduce, Apache Spark, Apache Hive, Apache Pig.
