Another mention linked to this: for efficiency explanations, and also to eliminate battle problems whenever saving nodes

we deferred the actual processing to Drupal’s waiting line program. That nicely eliminated race problems around opening nodes during node conserve and held the user user interface smooth and responsive.

There seemed to be an added necessity: considering that the inbound facts is frequently unfinished we had a need to in addition transfer information from For that we developed a two layer program: you’re a generic PHP plan by using the Guzzle library that indicated Rotten Tomatoes content material as PHP objects, whilst additional after that bridges that system to create Drupal nodes inhabited from Rotten Tomatoes facts. We then matched up Rotten Tomatoes movies and studies because of the client’s supply information and allowed editors to choose to utilize data from Rotten Tomatoes and only their own where appropriate. That information got merged in throughout indexing process nicely, therefore as soon as information is in Elasticsearch it does not matter in which it originated in. We furthermore subjected Critic Evaluations to Elasticsearch and in order that customer applications could discover reviews of films and consumer ratings prior to purchasing.

Incoming requests from client programs never ever hit Drupal. They only ever before strike the Silex app machine.

The Silex app doesn’t have to complete a great deal. The wire format we chosen the Hypertext program Language, or HAL. HAL try an easy to use JSON-based hypermedia structure used by Drupal 8, Zend Appagility, as well as others, and is also an IETF draft specification. It keeps a really robust PHP collection offered that we could actually use. Since Elasticsearch already stores and comes back JSON it was unimportant to map stuff from Elasticsearch into HAL. The heavy-lifting was simply in drawing and affixing the right hypermedia hyperlinks and embedded beliefs. Search term alongside research queries are simply passed away to Elasticsearch together with results accustomed load the appropriate registers.

Eventually, we wrapped the HAL item up in Symfony’s reaction item, ready our HTTP caching parameters and ETags, and sent the content on its way.

A huge benefit of the split-architecture is spinning up a brand new Silex case are insignificant. There’s no important setup beyond pinpointing the Elasticsearch machine to utilize, and most code was pulled down via Composer. That implies rotating up numerous instances of the API servers for redundancy, high-availability, or efficiency was without any efforts. We don’t have to fret, however; the API is read-only, thus with proper using HTTP headers and a fundamental Varnish server before they the API try interestingly snappy.

The Upshot

A large part of Drupal’s readiness as a CMS is actually realizing that it’sn’t the be-all end-all response to all difficulties.

For Ooyala and its clients, Drupal is just the thing for handling content, but not for offering a web API. Luckily, Palantir’s comprehension of the upcoming Drupal 8 production and its particular reliance throughout the Symfony pipeline let’s combine Drupal with Silex – that is ideal for providing a web site API yet not all of that hot for controlling and curating material. Ultimately, Palantir chose the best tool for the task, in addition to project benefited from this greatly.

Ooyala is now offering a powerful and reliable API that will be capable offer clients programs we never ever actually handled ourselves; Ooyala’s clients get what they want; end users posses a fast and receptive internet provider powering their particular mass media solutions. In addition to that, Palantir met with the opportunity to have our hands dirty with another member of the Symfony family members – a financial investment that’ll pay lasting with Drupal 8 while the expanding popularity of Symfony within PHP ecosystem.

Perfect for Ooyala; an excellent option for Palantir; an excellent option for town.
