Hello team,

In our use case with Medusa, we encountered an issue with rate limiting. To address this, we introduced a 100ms sleep as a workaround to avoid exceeding the limit.

I propose adding a configurable flag for this behavior in the main release to make it more flexible for others facing similar issues.

As I’m not deeply familiar with Go or the Medusa codebase, I would greatly appreciate any guidance or suggestions on the best way to implement this.

Thank you!

Howdy -- just wanted to mention that I needed this functionality as well so I'm using a modified version of your branch. I actually needed it for writes instead of reads -- it would be cool if you added this to the write functionality as well. =) Either way I wanted to add a thumbs up and note that more than one group needs it. Thanks!
