Overview

The “Store” is the middle layer in the WCC::Contentful gem. It exposes an API that implements the configured content delivery strategy.

The different content delivery strategies require different store implementations.

direct: Uses the WCC::Contentful::Store::CDNAdapter to wrap the Contentful CDN, providing an API consistent with the other stores. Any query made to the CDNAdapter will be immediately passed through to the API. The CDNAdapter does not implement #index because it does not care about updates coming from the Sync API.
lazy_sync: Uses the Contentful CDN in combination with an ActiveSupport::Cache implementation in order to respond with the cached data where possible, saving your CDN quota. The cache is kept up-to-date via the Sync Engine and the WCC::Contentful::SyncEngine::Job. It is correct, but not complete.
eager_sync: Uses one of the full store implementations to store the entirety of the Contentful space locally. All queries are run against this local copy, which is kept up to date via the Sync Engine and the WCC::Contentful::SyncEngine::Job. The local store is correct and complete.

The currently configured store is available on WCC::Contentful::Services.instance.store
