we deferred the particular processing off to Drupal’s waiting line system. That perfectly averted competition problems around being able to access nodes during node save and held the user screen rapid and responsive.

There was one other prerequisite: Since the inbound information is often incomplete we wanted to in addition transfer data from For this we developed a-two covering system: One is a simple PHP plan utilising the Guzzle library that indicated Rotten Tomatoes material as PHP stuff, whilst the more after that links that system to produce Drupal nodes filled from Rotten Tomatoes facts. We subsequently harmonized Rotten Tomatoes flicks and feedback with all the customer’s source data and allowed editors to elect to utilize facts from Rotten Tomatoes in favor of their in which appropriate. That data was combined in while in the indexing process also, so when data is in Elasticsearch it doesn’t matter in which it originated. We furthermore subjected Critic product reviews to Elasticsearch too to make certain that client applications could see reviews of movies and user reviews prior to purchasing.

Incoming desires from clients programs never ever struck Drupal. They merely actually ever hit the Silex application machine.

The Silex application doesn’t need to accomplish a lot. When it comes down to line format we chosen the Hypertext Application code, or HAL. HAL is an easy to use JSON-based hypermedia structure used by Drupal 8, Zend Appagility, yet others, and is an IETF draft requirements. In addition keeps a very sturdy PHP collection available that people had the ability to make use of. Since Elasticsearch already shops and returns JSON it was trivial to map stuff from Elasticsearch into HAL. The hard work was merely in deriving and affixing the best hypermedia backlinks and embedded beliefs. Keyword alongside browse questions are simply passed right through to Elasticsearch as well as the information always load the right information.

At long last, we covered the HAL item up in Symfony’s impulse item, arranged all of our HTTP caching variables and ETags, and sent the message returning.

A big advantageous asset of the split-architecture is the fact that spinning up a new Silex instance is trivial. There’s no meaningful configuration beyond pinpointing the Elasticsearch servers to utilize, and a lot of code is actually pulled down via Composer. This means rotating up several cases of the API host for redundancy, high-availability, or overall performance are without any perform. We failed to want to fret, though; the API are read-only, very with correct utilization of HTTP headers and a standard Varnish servers in front of they the API are surprisingly snappy.

The Upshot

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

For Ooyala and its consumers, Drupal is perfect for dealing with information, but not for serving a web site API. Luckily, Palantir’s familiarity with the coming Drupal 8 release and its own dependence on Symfony pipeline let us set Drupal with Silex – that’s ideal for helping an internet API not all those things hot for dealing with and curating material. Fundamentally, Palantir chose the proper instrument for the task, in addition to task benefited out of this considerably.

Ooyala presently has a robust and trustworthy API this is certainly able to offer client solutions we never ever also handled our selves; Ooyala’s customers see what they need; clients need an easy and responsive online solution powering her mass media software. On top of that, Palantir encountered the chance to have our very own fingers dirty with another member of the Symfony families – an investment that will pay-off lasting with Drupal 8 additionally the raising interest in Symfony inside the PHP ecosystem.

An excellent option for Ooyala; an excellent option for Palantir; an excellent option for the community.
