Cache::PostgresCacheStore

Crystal CI GitHub release

A cache store implementation which stores everything in the Postgres database, using crystal-pg as the backend.

Cache::PostgresCacheStore is a Crystal cache backed by a Postgres UNLOGGED table and text column.

Installation

  1. Add the dependency to your shard.yml:

    dependencies:
  postgres_cache_store:
    github: crystal-cache/postgres_cache_store

  2. Run shards install

Usage

Before using this shard make sure you have created Postgres database. For example cache_production:

psql -c 'CREATE DATABASE cache_production;' -U postgres

A Postgres database can be opened with:

db = DB.open("postgres://postgres@localhost/cache_production")

Open and use the new cache instance:

require "postgres_cache_store"

cache = Cache::PostgresCacheStore(String, String).new(1.minute, db)

cache.write("foo", "bar")

cache.read("foo") # => "bar"
