Use one instance of NodeCache per DB collection...

[LucasBrazi06]

I would like to use the TTL at NodeCache's instance level and not per record.

Then I'll be notified only once when the instance data is expired and I will reload ALL the cache at once.

When instance is created, the TTL provided is applied to the instance

    const nodeCache = new NodeCache( {
      instanceTTL: 600,   // Instance TTL
      checkperiod: 100,
    });

This notification should be called only once after instance expiration and I will put the code here to reload the whole cache:

    nodeCache.on( "instance_expired", (instance: NodeCache) => {
        // Reload the whole cache here from the DB
    });

Is it possible?

Can I work on this?

From what i understood, this is what youre asking for:

const nodeCache1 = new NodeCache( {
     stdTTL: 600,   // TTL for nodeCache1 
     checkperiod: 100,
});

const nodeCache2 = new NodeCache( {
     stdTTL: 400,   // TTL for nodeCache2
     checkperiod: 100,
});

// . . .

nodeCache2.on( "key_expired", (key, value) => {
       //  . . .
});

nodeCache1.on( "key_expired", (key, value) => {
       //  . . .
});

And, yes thats possible
