<p>Writes a single data record into an Amazon Kinesis data stream. Call <code>PutRecord</code> 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.</p> <note> <p>When invoking this API, it is recommended you use the <code>StreamARN</code> input parameter rather than the <code>StreamName</code> input parameter.</p> </note> <p>You must specify the name of the stream that captures, stores, and transports the data; a partition key; and the data blob itself.</p> <p>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.</p> <p>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.</p> <p>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 <code>ExplicitHashKey</code> parameter.

To guarantee strictly increasing ordering, write serially to a shard and use the <code>SequenceNumberForOrdering</code> parameter. For more information, see <a href="https://docs.aws.amazon.com/kinesis/latest/dev/developing-producers-with-sdk.html#kinesis-using-sdk-java-add-data-to-stream">Adding Data to a Stream</a> in the <i>Amazon Kinesis Data Streams Developer Guide</i>.</p> <important> <p>After you write a record to a stream, you cannot modify that record or its order within the stream.</p> </important> <p>If a <code>PutRecord</code> request cannot be processed because of insufficient provisioned throughput on the shard involved in the request, <code>PutRecord</code> throws <code>ProvisionedThroughputExceededException</code>. </p> <p>By default, data records are accessible for 24 hours from the time that they are added to a stream. You can use <a>IncreaseStreamRetentionPeriod</a> or <a>DecreaseStreamRetentionPeriod</a> to modify this retention period.</p>
