Writes a single data record into an Amazon Kinesis data stream. Call
PutRecord
to send data into the stream for real-time ingestion and
subsequent processing, one record at a time. Each shard can support
writes up to 1,000 records per second, up to a maximum data write total
of 1 MiB per second.
You must specify the name of the stream that captures, stores, and transports the data; a partition key; and the data blob itself.
The data blob can be any type of data; for example, a segment from a log file, geographic/location data, website clickstream data, and so on.
The partition key is used by Kinesis Data Streams to distribute data across shards. Kinesis Data Streams segregates the data records that belong to a stream into multiple shards, using the partition key associated with each data record to determine the shard to which a given data record belongs.
Partition keys are Unicode strings, with a maximum length limit of 256
characters for each key. 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
Adding Data to a Stream
in the Amazon Kinesis Data Streams 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 increase over time and are specific to a shard within a
stream, not across all shards within a stream. To guarantee strictly
increasing ordering, write serially to a shard and use the
SequenceNumberForOrdering
parameter. For more information, see
Adding Data to a Stream
in the Amazon Kinesis Data Streams Developer Guide.
After you write a record to a stream, you cannot modify that record or its order within the stream.
If a PutRecord
request cannot be processed because of insufficient
provisioned throughput on the shard involved in the request, PutRecord
throws ProvisionedThroughputExceededException
.
By default, data records are accessible for 24 hours from the time that they are added to a stream. You can use IncreaseStreamRetentionPeriod or DecreaseStreamRetentionPeriod to modify this retention period.

Instances
:: Text | |

-> Text | |
-> PutRecord |
Create a value of PutRecord
with all optional fields omitted.
Use generic-lens or optics to modify other optional fields.
The following record fields are available, with the corresponding lenses provided for backwards compatibility:
$sel:explicitHashKey:PutRecord'
, putRecord_explicitHashKey
- The hash value used to explicitly determine the shard the data record is
assigned to by overriding the partition key hash.
$sel:sequenceNumberForOrdering:PutRecord'
, putRecord_sequenceNumberForOrdering
- 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 result when putting record n-1). If
this parameter is not set, records are coarsely ordered based on arrival
time.
$sel:streamName:PutRecord'
, putRecord_streamName
- The name of the stream to put the data record into.
$sel:data':PutRecord'
, putRecord_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).--
-- Note: This Lens
automatically encodes and decodes Base64 data.
-- The underlying isomorphism will encode to Base64 representation during
-- serialisation, and decode from Base64 representation during deserialisation.
-- This Lens
accepts and returns only raw unencoded data.
$sel:partitionKey:PutRecord'
, putRecord_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.
