Splits a shard into two new shards in the Kinesis data 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 a 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, the producers sending data into the specific shard
are suddenly sending more than previously anticipated. You can also call
to increase stream capacity, so that more Kinesis Data Streams 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 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 Split a Shard in the Amazon Kinesis Data Streams Developer Guide.
You can use DescribeStream to determine the shard ID and hash key values for

SplitShard is an asynchronous operation. Upon receiving a
request, Kinesis Data Streams immediately returns a response and sets the stream status

the stream status to

You can use
DescribeStream to check the status of the stream, which is
StreamStatus. If the stream is in the

SplitShard. If a stream is in

For .NET Core, PCL and Unity this operation is only available in asynchronous form. Please refer to SplitShardAsync.
