Sorry to bother you again, but I'd like to ask about cross-user processing, such as leaderboards and server-wide emails. These are very similar to singleton services. Can sharding help with this? How do you handle the pressure on these types of services?

How about discussing on Discord instead of here? Comments are not ideal for long conversations. There’s a Shardcake channel on the ZIO Discord.

[ZHE ZHANG](https://hashnode.com/@zhangjiji) I’d rather use Discord since other people can benefit from reading it. Potentially a GitHub issue if it’s specifically about Shardcake.
