// Updates the shard count of the specified stream to the specified number of
// shards. Updating the shard count is an asynchronous operation. Upon receiving
// the request, Kinesis Data Streams returns immediately and sets the status of the
// stream to UPDATING. After the update is complete, Kinesis Data Streams sets the
// status of the stream back to ACTIVE. Depending on the size of the stream, the
// scaling action could take a few minutes to complete. You can continue to read
// and write data to your stream while its status is UPDATING. To update the shard
// count, Kinesis Data Streams performs splits or merges on individual shards. This
// can cause short-lived shards to be created, in addition to the final shards.
// These short-lived shards count towards your total shard limit for your account
// in the Region. When using this operation, we recommend that you specify a target
// shard count that is a multiple of 25% (25%, 50%, 75%, 100%). You can specify any
// target value within your shard limit. However, if you specify a target that
// isn't a multiple of 25%, the scaling action might take longer to complete. This
// operation has the following default limits. By default, you cannot do the
// following:
//
// * Scale more than ten times per rolling 24-hour period per stream
//
// *
// Scale up to more than double your current shard count for a stream
//
// * Scale down
// below half your current shard count for a stream
//
// * Scale up to more than 10000
// shards in a stream
//
// * Scale a stream with more than 10000 shards down unless the
// result is less than 10000 shards
//
// * Scale up to more than the shard limit for
// your account
//
// For the default limits for an Amazon Web Services account, see
// Streams Limits
// (https://docs.aws.amazon.com/kinesis/latest/dev/service-sizes-and-limits.html)
// in the Amazon Kinesis Data Streams Developer Guide. To request an increase in
// the call rate limit, the shard limit for this API, or your overall shard limit,
// use the limits form
// (https://console.aws.amazon.com/support/v1#/case/create?issueType=service-limit-increase&limitType=service-code-kinesis).
