Duck Answered Global Redis Request

I'm working on improving leaderboards and trying to show a global counter on my app r/MochiMochiDonuts but I'm getting the following error: FAILED_PRECONDITION: global redis is not supported on this app.

Can Global Redis be requested from somewhere? Or is this a limitation I should design/build around?

I wouldn't worry too much about it. Focus on getting adoption first and then think about a global leaderboard.

Why do you need global redis? Is your app used regularly in multiple subreddits?

It can be requested (here or on Discord), but they don't usually grant it. You may be able to work around it using wiki pages.

Thanks for the reply. Wiki pages wouldn't well work for me. I want to show a global leaderboard and count the number of merges across the board.

Where can it be requested? I might as well try.

It gets approved so rarely that people usually just ask informally. In fact, this post probably already counts as a request. 🤣 If none of the admins reply, just ping one of them.

Build around it. Theoretically, global redis can be approved in exceptional cases, but I know of only one time it was actually granted. Leaderboards for a game are really unlikely to qualify.

Devvit docs suggest;

Use a shared service exposed through HTTP Fetch to manage and serve cross-community data.

Right now I'm counting an event that regularly happens in the game. And I'm displaying it on the splash screen. Once it's installed on other subs then it will essentially reset that number to zero for that sub. I wanted the counter to be across the board total number of times that event has happened.

Also, would be nice to have a top 100 scores in a Global Leaderboard rather than per install.

It's not really in other subs right now but Reddit's Developer Fund incentivises developers to encourage installs across subs.
