Key-value store

The key-value store provides a simple persistence layer for the players.

Coherence.Runtime.KvStore

The player needs need to be logged in to use the key-value store.

This class provides the methods to set, get and unset key-value pairs. This is executed within the context of the currently logged in player.

public static class KvStore
{
    // Sets a value
    // key: lowercase letters, numbers, underscore, dash
    // val: any string (null is not allowed)
    public static void Set(string key, string val)
    
    // Gets a value
    // key: lowercase letters, numbers, underscore, dash
    public static string Get(string key)
    
    // Unsets a value, removing it from the store
    // key: lowercase letters, numbers, underscore, dash
    public static void Unset(string key)
}

Example

Coherence.Runtime.KvStore.Set("foo", "1");

var foo = Coherence.Runtime.KvStore.Get("foo");
Debug.Log(string.Format("foo={0}", foo)); // foo=1

Coherence.Runtime.KvStore.Unset("foo");

Limitations

Size: there are no limits to the number of stored key/values as long as the total size is less than 256 kB.

Requests: Set/Get/Unset can be called unlimited amount of times but the execution may be throttled.
