// You can scale by provisioning multiple shards per stream while considering
// service limits (for more information, see Streams Limits (http://docs.aws.amazon.com/kinesis/latest/dev/service-sizes-and-limits.html)
// in the Amazon Kinesis Streams Developer Guide). Your application should have
// one thread per shard, each reading continuously from its stream. To read

// returns a new shard iterator in NextShardIterator. Specify the shard iterator
// returned in NextShardIterator in subsequent calls to GetRecords. Note that
// if the shard has been closed, the shard iterator can't return more data and
// GetRecords returns null in NextShardIterator. You can terminate the loop
// when the shard is closed, or when the shard iterator reaches the record with

// process.
//
// Each data record can be up to 1 MB in size, and each shard can read up to
// 2 MB per second. You can ensure that your calls don't exceed the maximum
// supported size or throughput by using the Limit parameter to specify the

// record size when determining this limit.
//
// The size of the data returned by GetRecords varies depending on the utilization
// of the shard. The maximum size of data that GetRecords can return is 10 MB.
// If a call returns this amount of data, subsequent calls made within the next
// 5 seconds throw ProvisionedThroughputExceededException. If there is insufficient
// provisioned throughput on the shard, subsequent calls made within the next
// 1 second throw ProvisionedThroughputExceededException. Note that GetRecords
// won't return any data when it throws an exception. For this reason, we recommend
// that you wait one second between calls to GetRecords; however, it's possible
// that the application will get exceptions for longer than 1 second.

// (a data producer is any data source putting data records into a stream, for

// 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 (http://docs.aws.amazon.com/kinesis/latest/dev/developing-producers-with-sdk.html#kinesis-using-sdk-java-add-data-to-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 (http://docs.aws.amazon.com/kinesis/latest/dev/developing-producers-with-sdk.html#kinesis-using-sdk-java-add-data-to-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.

// Writes multiple data records into an Amazon Kinesis stream in a single call
// (also referred to as a PutRecords request). Use this operation to send data
// into the stream for data ingestion and processing.
//
// Each PutRecords request can support up to 500 records. Each record in the
// request can be as large as 1 MB, up to a limit of 5 MB for the entire request,
// including partition keys. 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; and an array of request Records, with each record in the array
// requiring a partition key and data blob. The record size limit applies to
// the total size of the partition key and data blob.
//
// 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 as input to a hash function
// that maps the partition key and associated data to a specific shard. 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. For more information, see Adding Data to a Stream (http://docs.aws.amazon.com/kinesis/latest/dev/developing-producers-with-sdk.html#kinesis-using-sdk-java-add-data-to-stream)
// in the Amazon Kinesis Streams Developer Guide.
//
// Each record in the Records array may include an optional parameter, ExplicitHashKey,
// which overrides the partition key to shard mapping. This parameter allows
// a data producer to determine explicitly the shard where the record is stored.
// For more information, see Adding Multiple Records with PutRecords (http://docs.aws.amazon.com/kinesis/latest/dev/developing-producers-with-sdk.html#kinesis-using-sdk-java-putrecords)
// in the Amazon Kinesis Streams Developer Guide.
//
// The PutRecords response includes an array of response Records. Each record
// in the response array directly correlates with a record in the request array
// using natural ordering, from the top to the bottom of the request and response.
// The response Records array always includes the same number of records as
// the request array.
//
// The response Records array includes both successfully and unsuccessfully
// processed records. Amazon Kinesis attempts to process all records in each
// PutRecords request. A single record failure does not stop the processing
// of subsequent records.
//
// A successfully-processed record includes ShardId and SequenceNumber values.
// The ShardId parameter identifies the shard in the stream where the record
// is stored. The SequenceNumber parameter is an identifier assigned to the
// put record, unique to all records in the stream.
//
// An unsuccessfully-processed record includes ErrorCode and ErrorMessage values.
// ErrorCode reflects the type of error and can be one of the following values:
// ProvisionedThroughputExceededException or InternalFailure. ErrorMessage provides
// more detailed information about the ProvisionedThroughputExceededException
// exception including the account ID, stream name, and shard ID of the record
// that was throttled. For more information about partially successful responses,

// Splits a shard into two new shards in the Amazon Kinesis stream to increase

//
// You can also use SplitShard when a shard appears to be approaching its maximum
// utilization; for example, the producers sending data into the specific shard
// are suddenly sending more than previously anticipated. You can also call
// SplitShard to increase stream capacity, so that more Amazon Kinesis applications
// can simultaneously read data from the stream for real-time processing.
//
// You must specify the shard to be split and the new hash key, which is the
// position in the shard where the shard gets split in two. In many cases, the
// new hash key might simply be the average of the beginning and ending hash
// key, but it can be any hash key value in the range being mapped into the
// shard. For more information about splitting shards, see Split a Shard (http://docs.aws.amazon.com/kinesis/latest/dev/kinesis-using-sdk-java-resharding-split.html)

//
// You can use DescribeStream to determine the shard ID and hash key values
// for the ShardToSplit and NewStartingHashKey parameters that are specified
// in the SplitShard request.
//
// SplitShard is an asynchronous operation. Upon receiving a SplitShard request,
// Amazon Kinesis immediately returns a response and sets the stream status
// to UPDATING. After the operation is completed, Amazon Kinesis sets the stream
// status to ACTIVE. Read and write operations continue to work while the stream
// is in the UPDATING state.
//
// You can use DescribeStream to check the status of the stream, which is returned
// in StreamStatus. If the stream is in the ACTIVE state, you can call SplitShard.
// If a stream is in CREATING or UPDATING or DELETING states, DescribeStream
// returns a ResourceInUseException.
//
