How does pushing logs directly into a Kinesis stream improve durability compared with batching them on the server?

  4. Records are retained indefinitely by default
Show the answer

Answer: A. Records are available within seconds, so they survive an application server failure

Producers push straight into the stream instead of batching on the server, so log data is not lost when a front end or application server fails.
