Understanding the basics of quantization in apache flink
What is Quantization in Apache Flink?
Quantization in Apache Flink refers to the process of transforming high-precision data into lower-precision formats to optimize computational efficiency and reduce storage requirements. This technique is particularly useful in stream processing, where large volumes of data are processed continuously. By reducing the precision of numerical data, quantization minimizes the memory footprint and accelerates processing times, making it ideal for real-time analytics and machine learning applications.
In Flink, quantization can be applied at various stages of the data pipeline, including preprocessing, feature extraction, and model inference. The framework's flexibility allows developers to implement custom quantization strategies tailored to specific use cases, ensuring that the trade-off between precision and efficiency aligns with business objectives.
