/**
 * <p>Splits a shard into two new shards in the Kinesis data stream, to increase the
 *             stream's capacity to ingest and transport data. <code>SplitShard</code> is called when
 *             there is a need to increase the overall capacity of a stream because of an expected
 *             increase in the volume of data records being ingested. This API is only supported for
 *             the data streams with the provisioned capacity mode.</p>
 *          <note>
 *             <p>When invoking this API, you must use either the <code>StreamARN</code> or the
 *                     <code>StreamName</code> parameter, or both. It is recommended that you use the
 *                     <code>StreamARN</code> input parameter when you invoke this API.</p>
 *          </note>
 *          <p>You can also use <code>SplitShard</code> 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
 *                 <code>SplitShard</code> to increase stream capacity, so that more Kinesis Data
 *             Streams applications can simultaneously read data from the stream for real-time
 *             processing. </p>
 *          <p>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 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, see <a href="https://docs.aws.amazon.com/kinesis/latest/dev/kinesis-using-sdk-java-resharding-split.html">Split a
 *                 Shard</a> in the <i>Amazon Kinesis Data Streams Developer
 *                 Guide</i>.</p>
 *          <p>You can use <a>DescribeStreamSummary</a> and the <a>ListShards</a> APIs to determine the shard ID and hash key values for the <code>ShardToSplit</code>
 *             and <code>NewStartingHashKey</code> parameters that are specified in the
 *                 <code>SplitShard</code> request.</p>
 *          <p>
 *             <code>SplitShard</code> is an asynchronous operation. Upon receiving a
 *                 <code>SplitShard</code> request, Kinesis Data Streams immediately returns a response
 *             and sets the stream status to <code>UPDATING</code>. After the operation is completed,
 *             Kinesis Data Streams sets the stream status to <code>ACTIVE</code>. Read and write
 *             operations continue to work while the stream is in the <code>UPDATING</code> state. </p>
 *          <p>You can use <a>DescribeStreamSummary</a> to check the status of the stream,
 *             which is returned in <code>StreamStatus</code>. If the stream is in the
 *                 <code>ACTIVE</code> state, you can call <code>SplitShard</code>.
 *             </p>
 *          <p>If the specified stream does not exist, <a>DescribeStreamSummary</a>
 *             returns a <code>ResourceNotFoundException</code>. If you try to create more shards than
 *             are authorized for your account, you receive a <code>LimitExceededException</code>. </p>
 *          <p>For the default shard limit for an Amazon Web Services account, see <a href="https://docs.aws.amazon.com/kinesis/latest/dev/service-sizes-and-limits.html">Kinesis
 *                 Data Streams Limits</a> in the <i>Amazon Kinesis Data Streams Developer
 *                 Guide</i>. To increase this limit, <a href="https://docs.aws.amazon.com/general/latest/gr/aws_service_limits.html">contact Amazon Web Services
 *                 Support</a>.</p>
 *          <p>If you try to operate on too many streams simultaneously using <a>CreateStream</a>, <a>DeleteStream</a>, <a>MergeShards</a>, and/or <a>SplitShard</a>, you receive a
 *                 <code>LimitExceededException</code>. </p>
 *          <p>
 *             <code>SplitShard</code> has a limit of five transactions per second per account.</p>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { KinesisClient, SplitShardCommand } from "@aws-sdk/client-kinesis"; // ES Modules import
 * // const { KinesisClient, SplitShardCommand } = require("@aws-sdk/client-kinesis"); // CommonJS import
 * // import type { KinesisClientConfig } from "@aws-sdk/client-kinesis";
 * const config = {}; // type is KinesisClientConfig
 * const client = new KinesisClient(config);
 * const input = { // SplitShardInput
 *   StreamName: "STRING_VALUE",
 *   ShardToSplit: "STRING_VALUE", // required
 *   NewStartingHashKey: "STRING_VALUE", // required
 *   StreamARN: "STRING_VALUE",
 *   StreamId: "STRING_VALUE",
 * };
 * const command = new SplitShardCommand(input);
 * const response = await client.send(command);
 * // {};
 *
 * ```
 *
 * @param SplitShardCommandInput - {@link SplitShardCommandInput}
 * @returns {@link SplitShardCommandOutput}
 * @see {@link SplitShardCommandInput} for command's `input` shape.
 * @see {@link SplitShardCommandOutput} for command's `response` shape.
 * @see {@link KinesisClientResolvedConfig | config} for KinesisClient's `config` shape.
 *
 * @throws {@link AccessDeniedException} (client fault)
 *  <p>Specifies that you do not have the permissions required to perform this
 *             operation.</p>
 *
 * @throws {@link InvalidArgumentException} (client fault)
 *  <p>A specified parameter exceeds its restrictions, is not supported, or can't be used.
 *             For more information, see the returned message.</p>
 *
 * @throws {@link LimitExceededException} (client fault)
 *  <p>The requested resource exceeds the maximum number allowed, or the number of concurrent

 *
 * @throws {@link ResourceInUseException} (client fault)
 *  <p>The resource is not available for this operation. For successful operation, the
 *             resource must be in the <code>ACTIVE</code> state.</p>
 *
 * @throws {@link ResourceNotFoundException} (client fault)
 *  <p>The requested resource could not be found. The stream might not be specified
 *             correctly.</p>
 *
 * @throws {@link ValidationException} (client fault)
