Caching

Novel's philosophy of low overhead affects the function of caching because it do not use traditional caching services.

Caching in Novel makes use of PostgreSQL's SKIP UNLOGGED feature. So the caching layer is within the database layer itself.

The cache is located in the cache table.

Usage

You can use the cache through

feature.ts

import cache from 'novel/cache';

await cache.set('key', value);

await cache.get('key');

The cache key is hashed and stored in the cache table.

cache.get(key: string)

You can get a cached value from the database through a simple function.

cache.set(key: string, value: any, ttl?: number)

You can set the value as well as a TTL for the key you want to set

cache.clear(key: string)

Remove a key from the cache.

cache.touch(key: string, ttl: number)

If you want to extend the TTL of a cached key.
