README ¶

localcache

import "github.com/guregu/localcache"

This is a DynamoDB wrapper that caches values in memory. Very experimental, don't use it.

Problems

This library has only been tested with guregu/dynamo, so it doesn't support things like KeyConditionExpression.
Projections don't work and will probably break lots of stuff.
Cache isn't configurable and doesn't expire properly.
Query cache for certain kinds of indexes won't be invalidated properly through certain operations

Perhaps one day I'll fix these!
