Question

Kinesis - why merge shards?

(A) To reduce the cost of the stream.
(B) To improve the performance of the stream.
(C) To increase the capacity of the stream.
(D) To make the stream easier to manage.

Answer 1

Merging shards in Amazon Kinesis is done to improve the performance and capacity of the stream, reduce management overhead, and optimize costs.

Step-by-step explanation:

In Amazon Kinesis, merging shards is done with the purpose of improving the performance and capacity of the stream. When you merge shards, you effectively combine multiple smaller shards into a single larger shard. This allows for the efficient processing of data and increases the stream's ability to handle higher throughputs.

By merging shards, you reduce the overhead associated with managing a larger number of shards and also optimize the cost of the stream. Additionally, merging shards can make the stream easier to manage as you have fewer individual shards to handle and monitor.
