Final answer:
In Kinesis Analytics, one Kinesis Processing Unit (KPU) provides 1 GB of memory for real-time data processing and analysis in Amazon Web Services.
Step-by-step explanation:
The memory size for 1 Kinesis Processing Unit (KPU) in Kinesis Analytics is 1 GB.
A Kinesis Processing Unit is the unit of computing power and memory that is allocated for streaming applications within the Kinesis Analytics service, which is a part of Amazon Web Services (AWS). A single KPU provides a stream processing application with the necessary resources to execute in real-time as it processes and analyzes streaming data.
In practical terms, if you are using Kinesis Analytics to build and run your streaming applications, understanding the resource allocation per KPU is critical for planning, scaling, and managing your applications effectively.
