Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

PutRecordsRequestEntry

Represents the output for PutRecords.

Contents

Data

The data blob to put into the record, which is base64-encoded when the blob is serialized. 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).

Type: Base64-encoded binary data object

Length Constraints: Minimum length of 0. Maximum length of 1048576.

Required: Yes

PartitionKey

Determines which shard in the stream the data record is assigned to. Partition keys are Unicode strings with a maximum length limit of 256 characters for each key. Amazon Kinesis Data Streams uses the partition key as input to a hash function that maps the partition key and associated data to a specific shard. Specifically, an MD5 hash function is used to map partition keys to 128-bit integer values and to map associated data records to shards. As a result of this hashing mechanism, all data records with the same partition key map to the same shard within the stream.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 256.

Required: Yes

ExplicitHashKey

The hash value used to determine explicitly the shard that the data record is assigned to by overriding the partition key hash.

Type: String

Pattern: 0|([1-9]\d{0,38})

Required: No
