The name helps understand a bit more what it is: REmote DIctionary Server. It is essentially a dictionary (key:value store) that runs on a server and can be accessed easily and quickly by multiple applications at the same time. Because of its speed and simplicity, it is used in many different ways in various applications. It also has a lot more features than a dictionary.

I don’t understand the goal or value of these polls/articles. It seems like they are wrong half the time. The last one was wrong: https://www.reuters.com/markets/rates-bonds/boc-hold-rates-this-year-high-risk-least-one-more-hike-2023-06-02/

If someone can explain, that would be nice!
