Introducing Built-in Image Data Source in Apache Spark 2.4

With recent advances in deep learning frameworks for image classification and object detection, the demand for standard image processing in Apache Spark has never been greater. Image handling and preprocessing have their specific challenges – for example, images come in different formats (eg., jpeg, png, etc.), sizes, and color schemes, and there is no easy way to test for correctness (silent failures).

Announcing Databricks Runtime 5.0

We’re excited to announce the general availability of Databricks Runtime 5.0. Included in this release is Spark 2.4. This release offers substantial performance increases within key areas of the platform. Benchmarking workloads have shown a 16% improvement in total execution time and Databricks Delta benefits from substantial improvements to metadata caching, improving query latency by 30%. Beyond these powerful performance improvements we’ve packed this release with many new features and improvements. I’ll highlight some of these now.

Simplifying Change Data Capture with Databricks Delta

A common use case that we run into at Databricks is that customers looking to perform change data capture (CDC) from one or many sources into a set of Databricks Delta tables. These sources may be on-premises or in the cloud, operational transactional stores, or data warehouses. The common glue that binds them all is they have change sets generated:

MLflow v0.7.0 Features New R API by RStudio

Today, we’re excited to announce MLflow v0.7.0, released with new features, including a new MLflow R client API contributed by RStudio. A testament to MLflow’s design goal of an open platform with adoption in the community, RStudio’s contribution extends the MLflow platform to a larger R community of data scientists who use RStudio and R programming language.  R is the third language supported in MLflow after Python and Java.
