Why Data Chain of Custody is Essential to Reducing Product Liability Risks

When a market grows as quickly as implantable medical devices, set to top a staggering $153.8 billion by 2026, the potential risk to patients can rise as well. As implantable medical devices proliferate, so do the number of costly, life-threatening, and reputation-tarnishing recalls. A single large recall can account for millions of device units.

Real-time log aggregation with Apache Flink Part 2

We are continuing our blog series about implementing real-time log aggregation with the help of Flink. In the first part of the series we reviewed why it is important to gather and analyze logs from long-running distributed jobs in real-time. We also looked at a fairly simple solution for storing logs in Kafka using configurable appenders only. As a reminder let’s review our pipeline again

Day in the Life of a Cloudera Data Platform Admin

Cloudera Data Platform (CDP) on Public Cloud makes being an admin for a big data platform even easier thanks to SDX. Watch me spend a day at a temp position for Aperture Cybertronics as their Data Admin. I'll quickly deploy clusters, grants users access, and change performance settings such as autoscaling for the Aperture Cybertornics' staff.

Benchmarking Ozone: Cloudera's next-generation Storage for CDP

Apache Hadoop Ozone was designed to address the scale limitation of HDFS with respect to small files and the total number of file system objects. On current data center hardware, HDFS has a limit of about 350 million files and 700 million file system objects. Ozone’s architecture addresses these limitations[4]. This article compares the performance of Ozone with HDFS, the de-facto big data file system.

Disk and Datanode Size in HDFS

This blog discusses answers to questions like what is the right disk size in datanode and what is the right capacity for a datanode. A few of our customers have asked us about using dense storage nodes. It is certainly possible to use dense nodes for archival storage because IO bandwidth requirements are usually lower for cold data. However the decision to use denser nodes for hot data must be evaluated carefully as it can have an impact on the performance of the cluster.
