Pagination & Retries

The shape of eventually-consistent, rate-limited, list-heavy APIs, and why paginators, waiters, and retry logic exist to tame them in boto3 and AWS SDK v3.

Paginate your first list operation and handle a throttling error in both Python (boto3) and TypeScript (AWS SDK v3), plus configuring retries and reading page counts.

Automatic page iteration with get_paginator and paginateXxx async iterators versus manual NextToken / ContinuationToken handling, plus page-size control and JMESPath search.

Using boto3 get_waiter().wait() and SDK v3 waitUntilXxx to poll until a resource reaches a target state, tuning delay and max attempts, and avoiding tight-loop polling anti-patterns.

Catching specific AWS error codes reliably across languages: botocore ClientError and modeled client.exceptions in boto3 versus typed exception classes and error.name in AWS SDK v3.

Defaults every service integration should set explicitly for pagination, waiters, retries, error handling, and idempotency across boto3 and AWS SDK v3.
