BedrockCacheTTL

type BedrockCacheTTL = CacheTTL;

Defined in: src/models/bedrock.ts:147

TTL durations accepted by Bedrock for prompt-cache checkpoints.

Bedrock accepts '5m' (default) and '1h', and validates the value server-side, rejecting unsupported values with ValidationException.

Bedrock also requires checkpoint TTLs to be non-increasing across toolConfig → system → messages — setting a longer TTL on a later checkpoint than an earlier one will be rejected by the service.
