**To merge shards**
The following ``merge-shards`` example merges two adjacent shards with IDs of shardId-000000000000 and shardId-000000000001 in the specified data stream and combines them into a single shard. ::
aws kinesis merge-shards \
--stream-name samplestream \
--shard-to-merge shardId-000000000000 \
--adjacent-shard-to-merge shardId-000000000001
This command produces no output.
