Another notice regarding this: for abilities grounds, and to avoid race ailments when saving nodes

we deferred the control off to Drupal’s queue program. That neatly prevented race problems around being able to access nodes during node conserve and stored the consumer program smooth and receptive.

There seemed to be one other prerequisite: because the inbound data was often incomplete we necessary to additionally transfer information from For that we built a-two coating program: One is a generic PHP bundle with the Guzzle collection that conveyed Rotten Tomatoes material as PHP objects, whilst the other subsequently bridges that system to create Drupal nodes inhabited from Rotten Tomatoes data. We subsequently matched up Rotten Tomatoes motion pictures and product reviews with all the client’s origin facts and allowed editors to choose to utilize information from Rotten Tomatoes in support of their particular where appropriate. That facts was actually joined in through the indexing process too, therefore once information is in Elasticsearch it does not matter in which they came from. We furthermore revealed Critic Studies to Elasticsearch too making sure that customer software could see recommendations of videos and consumer score prior to purchasing.

Incoming needs from client programs never ever strike Drupal. They merely ever before strike the Silex application host.

The Silex app does not even have to-do much. Your line format we chosen the Hypertext Application code, or HAL. HAL is actually a very simple JSON-based hypermedia format utilized by Drupal 8, Zend Appagility, yet others, and is also an IETF draft specification. Additionally provides a tremendously robust PHP collection offered that individuals had the ability to make use of. Since Elasticsearch currently storage and profits JSON it had been trivial to map items from Elasticsearch into HAL. The heavy lifting ended up being only in drawing and connecting the correct hypermedia backlinks and embedded beliefs. Key phrase along with other search queries had been merely passed away right through to Elasticsearch while the effects familiar with stream the correct files.

Eventually, we wrapped the HAL object up in Symfony’s impulse object, ready our very own HTTP caching details and ETags, and sent the content coming.

A big advantageous asset of the split-architecture is that rotating up another Silex case try trivial. There is absolutely no significant setting beyond pinpointing the Elasticsearch host to use, and the majority of rule is pulled down via Composer. It means spinning up numerous cases of the API servers for redundancy, high-availability, or results try basically no efforts. We didn’t want to fret, however; the API is actually read-only, very with proper usage of HTTP headers and an elementary Varnish server facing it the API is remarkably snappy.

The Upshot

A huge part of Drupal’s readiness as a CMS try recognizing that it isn’t the be-all end-all reply to all dilemmas.

For Ooyala as well as its people, Drupal was great for managing content material, although not for serving a web API. Thankfully, Palantir’s understanding of the coming Drupal 8 release and its dependence throughout the Symfony pipeline permit us to combine Drupal with Silex – basically an excellent option for providing a Web API although not all that hot for handling and curating contents. Fundamentally, Palantir chose the right instrument to do the job, therefore the job benefited from this significantly.

Ooyala is now offering a robust and dependable API that is able to provide client software we never ever even handled our selves; Ooyala’s customers see what they need; end users posses an easy and receptive internet services powering their particular news programs. In addition, Palantir had the possible opportunity to bring our very own hands dirty with another person in the Symfony household – an investment that’ll pay lasting with Drupal 8 in addition to expanding interest in Symfony within the PHP environment.

Ideal for Ooyala; perfect for Palantir; an excellent option for the community.
