Cache::MySqlCacheStore

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

Installation

1. Add the dependency to your shard.yml:

   dependencies:
     mysql_cache_store:
       github: crystal-cache/mysql_cache_store
   

2. Run shards install

Usage

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

mysql -u root

mysql> CREATE DATABASE cache_production character set utf8mb4 collate utf8mb4_unicode_ci;

A MySQL database can be opened with:

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

Open and use the new cache instance:

require "mysql_cache_store"

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

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

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

Development

Run specs

Before run specs make sure you have created MySQL database `cache_test

mysql -u root

mysql> CREATE DATABASE cache_test character set utf8mb4 collate utf8mb4_unicode_ci;
