Record - Amazon Kinesis Data Streams Service


The unit of data of the Kinesis data stream, which is composed of a sequence number, a partition key, and a data blob.



The data blob. The data in the blob is both opaque and immutable to Kinesis Data Streams, which does not inspect, interpret, or change the data in the blob in any way. When the data blob (the payload before base64-encoding) is added to the partition key size, the total size must not exceed the maximum record size (1 MiB).
