we deferred the specific running off to Drupal’s waiting line system. That nicely averted race conditions around opening nodes during node save and held the consumer user interface rapid and responsive.

There seemed to be another need: Because incoming information was typically unfinished we had a need to also transfer facts from For the we built a two layer system: a person is a general PHP bundle with the Guzzle collection that shown Rotten Tomatoes content material as PHP stuff, whilst the various other then links that system generate Drupal nodes inhabited from Rotten Tomatoes information. We after that harmonized Rotten Tomatoes movies and feedback with all the customer’s supply information and permitted editors to elect to make use of facts from Rotten Tomatoes in support of their in which appropriate. That facts is combined in while in the indexing techniques and, therefore as soon as information is in Elasticsearch it does not matter where it originated from. We in addition subjected Critic product reviews to Elasticsearch besides to ensure that client software could discover analysis of films and user ranks before buying.

Incoming requests from clients software never hit Drupal. They merely actually ever strike the Silex application machine.

The Silex application doesn’t have even accomplish much. When it comes down to wire format we selected the Hypertext program code, or HAL. HAL are a simple JSON-based hypermedia style used by Drupal 8, Zend Appagility, yet others, and is also an IETF draft specification. It provides an extremely powerful PHP collection readily available that individuals had the ability to utilize. Since Elasticsearch already shops and returns JSON it actually was trivial to map things from Elasticsearch into HAL. The heavy-lifting is merely in drawing and connecting the right hypermedia hyperlinks and embedded prices. Keyword and various other lookup inquiries had been merely passed through to Elasticsearch and also the effects accustomed stream the correct registers.

Finally, we covered the HAL item up in Symfony’s Response item, arranged all of our HTTP caching details and ETags, and delivered the message returning.

A big advantage of the split-architecture usually rotating up a fresh Silex instance was insignificant. There is absolutely no significant setup beyond identifying the Elasticsearch servers to make use of, and the majority of code was pulled down via author. Which means spinning up numerous instances of the API servers for redundancy, high-availability, or results is actually without any operate. We did not must worry, however; the API is actually read-only, so with appropriate utilization of HTTP headers and a simple Varnish host before it the API is actually surprisingly snappy.

The Upshot

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

For Ooyala and its own consumers, Drupal was perfect for controlling articles, however for providing a web API. Happily, Palantir’s comprehension of the future Drupal 8 release and its own reliance throughout the Symfony pipeline why don’t we combine Drupal with Silex – and is an excellent option for offering an internet API however everything hot for managing and curating content. Fundamentally, Palantir find the right tool to do the job, additionally the venture gained with this significantly.

Ooyala presently has a sturdy and trustworthy API that will be capable provide client programs we never ever actually touched ourselves; Ooyala’s customers see what they need; customers need an easy and responsive Web service running their particular media software. And also, Palantir met with the opportunity to have our hands dirty with another member of the Symfony parents – a financial investment which will pay off long-term with Drupal 8 together with growing popularity of Symfony inside the PHP ecosystem.

Perfect for Ooyala; just the thing for Palantir; an excellent option for town.
