- that the iterator points to, `GetRecords` returns an empty
- list. Note that it might take multiple calls to get to a
- portion of the shard that contains records.
-
- You can scale by provisioning multiple shards. Your
- application should have one thread per shard, each reading
- continuously from its stream. To read from a stream
- continually, call `GetRecords` in a loop. Use GetShardIterator
- to get the shard iterator to specify in the first `GetRecords`
- call. `GetRecords` 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
- the sequence number or other attribute that marks it as the
- last record to process.
-
- Each data record can be up to 50 KB 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 maximum number of records
- that `GetRecords` can return. Consider your average record
- size when determining this limit. For example, if your average
- record size is 40 KB, you can limit the data returned to about
- 1 MB per call by specifying 25 as the limit.
-
- The size of the data returned by `GetRecords` will vary
- depending on the utilization of the shard. The maximum size of
- data that `GetRecords` can return is 10 MB. If a call returns
- 10 MB 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.
-
- To detect whether the application is falling behind in
- processing, add a timestamp to your records and note how long
- it takes to process them. You can also monitor how much data
- is in a stream using the CloudWatch metrics for write
- operations ( `PutRecord` and `PutRecords`). For more
- information, see `Monitoring Amazon Kinesis with Amazon
- CloudWatch`_ in the Amazon Kinesis Developer Guide .

- """
- Puts (writes) multiple data records from a producer into an
- Amazon Kinesis stream in a single call (also referred to as a
- `PutRecords` request). Use this operation to send data from a
- data producer into the Amazon Kinesis stream for real-time
- ingestion and processing. Each shard can support up to 1000
- records written per second, up to a maximum total of 1 MB data
- written 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 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 `Partition Key`_
- in the Amazon Kinesis 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`_ in the Amazon Kinesis 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.
-
- Data records are accessible for only 24 hours from the time
- that they are added to an Amazon Kinesis stream.

- Splits a shard into two new shards in the stream, to increase
- the stream's capacity to ingest and transport data.
- `SplitShard` is called when there is a need to increase the
- overall capacity of stream because of an expected increase in
- the volume of data records being ingested.
-
- You can also use `SplitShard` when a shard appears to be
- approaching its maximum utilization, for example, when the set
- of 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`_ in the Amazon Kinesis Developer Guide .
-
- 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`.
-
- If the specified stream does not exist, `DescribeStream`
- returns a `ResourceNotFoundException`. If you try to create
- more shards than are authorized for your account, you receive
- a `LimitExceededException`.
-
- The default limit for an AWS account is 10 shards per stream.
- If you need to create a stream with more than 10 shards,
- `contact AWS Support`_ to increase the limit on your account.
-
- If you try to operate on too many streams in parallel using
- CreateStream, DeleteStream, MergeShards or SplitShard, you
- receive a `LimitExceededException`.
-
- `SplitShard` has limit of 5 transactions per second per
- account.
