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,
Amazon Kinesis returns immediately and sets the status of the stream to
After the update is complete, Amazon Kinesis 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
To update the shard count, Amazon Kinesis performs splits or merges on individual shards. This can cause short-lived shards to be created, in addition to the final shards. We recommend that you double or halve the shard count, as this results in the fewest number of splits or merges.
This operation has the following limits, which are per region per account unless otherwise noted:
scale more than twice per rolling 24 hour period
scale up above double your current shard count
scale down below half your current shard count
scale up above 200 shards in a stream
scale a stream with more than 200 shards down unless the result is less than 200 shards
scale up above the shard limits for your account
For PCL and Unity this operation is only available in asynchronous form. Please refer to UpdateShardCountAsync.
