Learn Before
An LLM inference server handles a mix of long document summarization requests and short, interactive chat queries. Operators observe that chat queries experience high latency whenever a long document's initial processing pass is running. To mitigate this, they implement a system that breaks the initial input of long documents into smaller segments, processing each segment in a separate forward pass to incrementally build the necessary cache. Which statement best evaluates the primary trade-off of this change?

Optimizing Inference Scheduling
An LLM inference system is using a method to process a long input sequence that has been divided into several segments or 'chunks'. Arrange the following steps in the correct chronological order to describe how the system incrementally builds the Key-Value (KV) cache for the entire input before starting to generate a response.
