Minigames Coins, where storage data?

I want to make coins manager for minigames, one game = other coins like in hypixel
where i should storage data?
in redis?
like:
gameName: UUID->COINS
gameName2:UUID->COINS
or mysql
like:
ID|uuid|name|oneGameCoins|twoGameCoins
or
ID|uuid|name|jsonSerializedCoins
what is the best way?
of course when i choose mysql i will make cache or somethink like this

 

Alternatively you could use a YAML file, specified as a config, it has methods for storing sections for each player, and a lot more.

 

Yep, use a configuration file, and make it custom named in case if you want more then 1 currency and because it looks better.

 

@TheEnderman, depending on the amount of players, that may end up being one big YAML file to store that much data.


@laruss I created a flat file kinda database recently which shares data across all my plugins in a single file for each player, and that has been working really well.
