Cache expiration about dataloader

[alexandrebodin]

Hi @tomitrescak

From my perspective DataLoader is though out to have a naive use of cache.

Moreover dataloader provides a cacheMap configuration to pass your own cache implementation. For example a lru-cache or a ttl-cache based.

The decision would be yours ;)

This NPM module is also a good option: expiry-map.

import ExpiryMap from 'expiry-map'

const myLoader = new DataLoader(someBatchLoadFn, {
  cacheMap: new ExpiryMap(200)
})

That makes perfect sense. Thanks.
