/**
*
* Writes a single data record into an Amazon Kinesis 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
* 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 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 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 Streams 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 a stream.
