PutRecord
to send data from the producer into the Amazon Kinesis 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 MB 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 Amazon Kinesis 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 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 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
Adding
Data to a Stream in 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
.
By default, data records are accessible for only 24 hours from the time that they are added to an Amazon Kinesis stream. This retention period can be modified using the DecreaseStreamRetentionPeriod and IncreaseStreamRetentionPeriod operations.

Exception | Condition |
---|---|
InvalidArgumentException | A specified parameter exceeds its restrictions, is not supported, or can't be used. For more information, see the returned message. |
ProvisionedThroughputExceededException | The request rate is too high, or the requested data is too large for the available throughput. Reduce the frequency or size of your requests. For more information, see Error Retries and Exponential Backoff in AWS in the AWS General Reference. |
ResourceNotFoundException | The requested resource could not be found. The stream might not be specified correctly, or it might not be in the ACTIVE state if the operation requires it. |
