Defined in:
(unknown)

Overview

Note:

When passing PutRecordsRequestEntry as input to an Aws::Client method, you can use a vanilla Hash:

{
  data: "data", # required
  explicit_hash_key: "HashKey",
  partition_key: "PartitionKey", # required
}

Represents the output for PutRecords.

Instance Attribute Details

#dataString

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 MB).

Returns:

  • (String)

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

#explicit_hash_keyString

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

Returns:

  • (String)

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

#partition_keyString

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 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.

Returns:

  • (String)

    Determines which shard in the stream the data record is assigned to.
