Kinesis Data Streams attempts to process all records in each <code>PutRecords</code> request. A single record failure does not stop the processing of subsequent records.

If you need to read records in the same order they are written to the stream, use <a>PutRecord</a> instead of <code>PutRecords</code>, and write to the same shard.</p> <p>A successfully processed record includes <code>ShardId</code> and <code>SequenceNumber</code> values.
