MemoryStoreService SortedMap Requests Failing

[vCaffy]

Reproduction Steps
Call any of the Memory Store Sorted Map functions. The two that I am using are, GetRangeAsync() and SetAsync(). Both are failing. This is happening in both studio and live games.

I haven’t made any changes recently to the MemoryStoreService calls.

Expected Behavior
No error.

Actual Behavior
They error with an error message of, “Request Failed.”

This is happening in our game. We rely on memory store service strictly for our server lists.

As well as another game, Criminality, that uses a similar system:

EDIT: We had close to 2k concurrent players and this completely ruined it. This has also happened numerous other times in the past. I am 100% sure I’m not using past the rate limit, or even the hard cap rate limit for that matter.

Roblox needs to address and negotiate this issue. Not many big games use memory store services, but the ones that do get heavily affected when they go down.

I had to stay up converting my system to use data stores because every single request resulted in a “Request Failed.” error.

We use sorted maps in our newest game to implement server/session locking for player data storage. Requests failing like this mean session locks don’t release properly and players are stuck waiting for their data to load until the lock times out

Hi, do you still experience this problem? There was indeed a problem with the MemoryStore service on Friday night between 8pm and midnight PST. It has operated normally since then though.

Nope, seems to be fine now from what I can tell
