Oracle Stream Explorer - configuring REST target

I've blogged about how to consume REST with Oracle Stream Explorer, this time we are going to take a look how to configure stream explorer to send events to a REST service.

We'll start by creating an exploration which summarises tweets per minute per each of the keywords we have:

Configuring a REST target 

Configuring a target is as simple as a few clicks. Just click the "Configure a target" button, select REST from the dropdown and enter your REST service url. Note that building the service is not in the scope of this blog, suffice to say it should expect parameters which your exploration emits.

Once the target is configured, deploy the exploration. One would expect the REST service to start receiving the events now. Instead, you might find an error in your oep server log

The key here is "Failed to set property 'cOUNT_of_text'". If you look at the first screenshot at the top, you'll notice that "COUNT_OF..." is automatically created when we summarise data in the exploration. However, Stream Explorer is - for reason unknown to me - at the moment not able to send this variable to the RESt service.


The workaround is quite simple. Maybe it's not obvious, but it's possible to rename exploration columns. Just click properties, select a property and then click on the pencil icon

In example above I renamed COUNT_of_text to tweetsPerMinute.

With this change just redeploy the exploration (and your REST service if required), and you should be able to receive data just fine.

Oracle Big Data Appliance X5-2 with Big Data SQL for the DBA

During January 2015, Oracle Executive Chairman and Chief Technology Officer Larry Ellison announced Oracle’s next-generation engineered systems, the fifth generation X5. The X5 portfolio of Oracle's Engineered Systems includes among others the X5 Big Data Appliance for Hadoop and NoSQL big data jobs. 

Big data is by far the most prevalent technology trend today, according to a recent study by consulting firm Capgemini. However, almost 80 percent of organizations have not achieved full-scale production of their big data initiatives.

Oracle Big Data Appliance is a high-performance, secure platform for running diverse workloads on Hadoop and NoSQL systems.

With the addition of Oracle Big Data SQL, Oracle Big Data Appliance extends Oracle’s industry-leading implementation of SQL to Hadoop and NoSQL systems, allowing to use existing SQL skills to query any data source.
