Simplify building big data pipelines for change data capture (CDC) and GDPR use cases. Databricks Delta, the next-generation unified analytics engine built on top of Apache Spark™, now supports the MERGE command, which allows you to efficiently upsert and delete records in your data lakes. MERGE dramatically simplifies how a number of common data pipelines...

Data versioning for reproducing experiments, rolling back, and auditing data We are thrilled to introduce time travel capabilities in Databricks Delta, the next-gen unified analytics engine built on top of Apache Spark, for all of our users. With this new feature, Delta automatically versions the big data that you store in your data lake, and...

Databricks is thrilled to announce our new optimized autoscaling feature. The new Apache Spark™-aware resource manager leverages Spark shuffle and executor statistics to resize a cluster intelligently, improving resource utilization. When we tested long-running big data workloads, we observed cloud cost savings of up to 30%. What’s the problem with current state-of-the-art autoscaling approaches? Today,...

Big data workloads require access to disk space for a variety of operations, generally when intermediate results will not fit in memory. When the required disk space is not available, the jobs fail. To avoid job failures, data engineers and scientists typically waste time trying to estimate the necessary amount of disk via trial and...

Databricks, the Unified Analytics Platform, has always been a cloud-first platform. We believe in the scalability and elasticity of the cloud so that customers can easily run their large production workloads and pay for exactly what they use. Hence, we have been charging our customers at per-second level granularity. Until last month, billing on AWS...

Secure your production workloads end-to-end with Databricks’ comprehensive access control system Databricks offers role-based access control for clusters and workspace to secure infrastructure and user code. Today, we are excited to announce role-based access control for Databricks Jobs as well so that users can easily control who can access the job output and control the...

Continuous integration and continuous delivery (CI/CD) is a practice that enables an organization to rapidly iterate on software changes while maintaining stability, performance and security. Continuous Integration (CI) practice allows multiple developers to merge code changes to a central repository. Each merge typically triggers an automated build that compiles the code and runs unit tests....

As the amount of data in an organization grows, more and more engineers, analysts and data scientists need to analyze this data using tools like Apache Spark. Today, IT teams constantly struggle to find a way to allocate big data infrastructure, budget among different users, and optimize performance. End-users like data scientists and analysts also...

Today we are excited to announce persistent clusters for analytics in Databricks. With persistent clusters, users no longer need to go through the laborious process of providing all the cluster and Apache Spark configuration every time they need a cluster. Admins can provide all the configurations to setup multiple clusters once and then allow users...
