Key-value store

Last updated 3 years ago

Motivation

coherence provides an API and a database for storing key-value pairs from within game sessions.

Description

The key/value store provides a simple way to store and retrieve data for the currently logged in player. For example, you could store player's score, email address, or any other data.

It is important to mention that this feature requires a .

Limitations

The keys must be alphanumerical strings, underscore or dash. Currently, only strings are accepted as values. If you need to store numbers or complex types like arrays, you have to convert them to strings.

The total amount of storred data (keys + values) cannot exceed 256 KB per player (TBD).

There is no limit how often the data is stored or retrieved.
