RU101 - Week2 - Error in First Video of "Capped Collections & Set Operations" Section

[mubashernaeem]

Dear Redis Team,

I would like to report an error identified in the first video of the "Capped Collections & Set Operations" section of week2 in the RU101 course. The error pertains to the explanation provided regarding the usage of the "ZREMRANGEBYRANK" command.

The video incorrectly states that "ZREMRANGEBYRANK" is used to trim the lowest-scoring element. However, based on my understanding and Redis documentation, "ZREMRANGEBYRANK" is actually used to remove elements from a sorted set by their rank/index range, rather than by their scores.

Could you please review and correct this information in the video, or add errata to ensure accuracy for learners?

Thank you for your attention to this matter.

Sincerely,
Mubasher Naeem
