Request Batcher

Software componentModel ServingModelsarc:RequestBatcher

An agent-layer component that accumulates multiple concurrent user queries and submits them to the model inference API as a single batch.

Responsibility. Trades individual time-to-first-token for aggregate inference throughput.

Also known as: Agent-layer request batching, Intelligent batching, API call batcher, Client-side batching, Request batching

Relationships

SHOULD apply only when optimizing for high concurrent load, since batching increases individual TTFT.
SHOULD batch similar operations (including verification API requests) into single requests, accepting slightly higher latency for throughput.
MAY pre-batch requests client-side when requests arrive too slowly for the server to form large batches.

As stated by the sources; verify before use.

Batch sizes of 4-16 optimise GPU utilisation, reducing average latency 30-50% while increasing tail latency 20-30% (Ch3.4).
Processing 10 requests in one batch uses less total infrastructure than 10 individual requests (Ch3.10).
BatchProcessor defaults: batch_size 32, max_wait 100 ms; typical savings 20-40% (Ref8.05).
Batching three 100-token requests needs 33% fewer GPU activations (Ref8.05).
