Databricks takes the human intervention out of Spark processing

PCWorld News

Databricks wants to make it possible to take humans out of the loop entirely when it comes to running complicated data analysis jobs.

The company, which offers a commercial version of Spark , now offers a tool to automate the setting up and executing of analysis written to run on the open source data processing platform.

“You can express very complicated workflows using this thing,” said Ali Ghodsi, Databricks’ director of engineering. “There is no human in the loop any more.”

Founded by several of the original developers of Spark, Databricks offers a commercial version of the platform designed to run on Amazon Web Services and eliminate many of the mundane chores of setting up and maintaining an in-house deployment.

Spark can be used to analyze very large data sets across multiple servers for tasks such as generating recommendations for an Internet service for users, or to predict future revenue of a company.

As customers get more comfortable with using big data, they are increasingly scheduling their analysis jobs to run on a regular basis, requiring an administrator to log into a console to coordinate all the steps needed to run the job.

The new feature for Databricks Cloud, called jobs, provides a way for administrators to set up schedules to run standalone Spark jobs at specified intervals. A user could schedule a Spark application to run on a specific Databricks cloud cluster at a scheduled time. Users can decide whether to use a dedicated cluster for maximum performance, or a cluster shared with other users to save money.

The service notifies the user when the task completes. The service also creates a log detailing if the task was completed successfully or not, and can alert the administrator if something goes awry.

In effect, the feature establishes a way to create a production pipeline, which is a series of jobs that execute automatically and in coordination with each other. An administrator can set up a workflow that executes two Spark jobs at the same time, and wait for both to finish. When both are completed, the workflow can then start another job that uses the results from the first two. If one of the two initial jobs fail, then the entire workflow can be terminated.

Jobs are written in Spark notebooks. Similar to iPython notebooks for Python, Spark notebooks are user-generated packages that contain all the components needed to run an interactive data analysis job across a cluster. Spark Notebooks can be written in Python, Scala, SQL, or a combination of each.

Pricing for Databricks is tiered, based on usage capacity, support model, and feature-set. It will start at several hundred dollars per month.
