`OperationStore` can use Redis to store persisted queries. Pass a `redis:` option when adding the plugin:
```ruby
class MySchema < GraphQL::Schema
use GraphQL::Pro::OperationStore, redis: Redis.new
end
```
(You can initialize `Redis` with any options you need.)
__Note:__ Be sure that this Redis instance is configured as a _persistent database_, not as a cache. You don't want it to throw away old keys!
