Aws.Kinesis.Commands.PutRecord

API Version: 2013-12-02

This operation puts a data record into an Amazon Kinesis stream from a producer. This operation must be called to send data from the producer into the Amazon Kinesis stream for real-time ingestion and subsequent processing. The PutRecord operation requires the name of the stream that captures, stores, and transports the data; a partition key; and the data blob itself. The data blob could be a segment from a log file, geographic/location data, website clickstream data, or any other data type.

The partition key is used to distribute data across shards. Amazon Kinesis segregates the data records that belong to a data stream into multiple shards, using the partition key associated with each data record to determine which shard a given data record belongs to.

Partition keys are Unicode strings, with a maximum length limit of 256 bytes. An MD5 hash function is used to map partition keys to 128-bit integer values and to map associated data records to shards using the hash key ranges of the shards. You can override hashing the partition key to determine the shard by explicitly specifying a hash value using the ExplicitHashKey parameter. For more information, see the Amazon Kinesis Developer Guide.

PutRecord returns the shard ID of where the data record was placed and the sequence number that was assigned to the data record.

Sequence numbers generally increase over time. To guarantee strictly increasing ordering, use the SequenceNumberForOrdering parameter. For more information, see the Amazon Kinesis Developer Guide.

If a PutRecord request cannot be processed because of insufficient provisioned throughput on the shard involved in the request, PutRecord throws ProvisionedThroughputExceededException.

Data records are accessible for only 24 hours from the time that they are added to an Amazon Kinesis stream.

data PutRecord

Constructors

PutRecord

Fields

putRecordData :: !ByteString

The data blob to put into the record. The maximum size of the data blob is 50 kilobytes (KB)

putRecordExplicitHashKey :: !(Maybe PartitionHash)

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

FIXME the specification is rather vague about the precise encoding of this value. The default is to compute it as an MD5 hash of the partition key. The API reference describes it as an Int128. However, it is not clear how the result of the hash function is encoded (big-endian or small endian, word size?) and how it is serialized to text, which is the type in the JSON serialization.

putRecordPartitionKey :: !PartitionKey

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

putRecordSequenceNumberForOrdering :: !(Maybe SequenceNumber)

Guarantees strictly increasing sequence numbers, for puts from the same client and to the same partition key. Usage: set the SequenceNumberForOrdering of record n to the sequence number of record n-1 (as returned in the PutRecordResult when putting record n-1). If this parameter is not set, records will be coarsely ordered based on arrival time.

putRecordStreamName :: !StreamName

The name of the stream to put the data record into.

Fields

putRecordResSequenceNumber :: !SequenceNumber

The sequence number identifier that was assigned to the put data record. The sequence number for the record is unique across all records in the stream. A sequence number is the identifier associated with every record put into the stream.

putRecordResShardId :: !ShardId

The shard ID of the shard where the data record was placed.
