In the "Architecting to Scale Quiz" #10 explanation, it’s stated that "the Kinesis Consumer Library (KCL)".
However, according AWS document (e.g.: https://aws.amazon.com/kinesis/data-streams/faqs/), KCL means Kinesis Client Library.
Could you please clarify?
Yes, that is a typo. Consumers use the Kinesis Client Library. I’ve pushed a correction.
