Previously limited to starting reads from the oldest retained record or new records post-consumption, the AT_TIMESTAMP shard iterator allows stream processing beginning exactly at or after a user-specified time. This supports workflows needing precise data replay, recovery after interruptions, or data skipping.
Integration with Amazon Kinesis Client Library through DynamoDB Streams Kinesis adapter enables common use cases such as auditing, debugging, and synchronization after point-in-time recovery exports. This feature is available across all commercial, GovCloud, and China AWS regions without additional cost beyond standard API usage.
