# async_counter_cache

Re-implements the Rails counter cache's UPDATEs to happen outside of the primary transaction that changes a record. Since that is not atomic anymore, this uses a `COUNT(*)` on the association.

Due to its possible slowness this is run in an ActiveJob by default, meaning the count is not immediately updated.

## Installation

Add this line to your application's Gemfile:

```ruby

gem 'async_counter_cache'

```

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install async_counter_cache

## Usage

```

has_many :posts, async_counter_cache: :posts_count

```
