Metro Area Clustering: Deployment and Configuration

This is the second blog in our series about ClustrixDB 9’s new Zones feature that supports creating Metro Area Clusters. If you missed the first blog “Database Metro Area Clustering Across Data Centers”, we recommend giving it a read since it provides a great overview of Metro Area Clustering. In this […]

Database Metro Area Clustering Across Data Centers

Data integrity, high availability, and easy disaster recovery have always been a major requirement of our ClustrixDB customers. Their OLTP applications are mission-critical and often customer- or consumer-facing, which makes the acceptable margin for error virtually nil.

The ClustrixDB Query Evaluation Model

Query Evaluation Model Recently we’ve started to dig into the internals of ClustrixDB, specifically How ClustrixDB Accomplishes Horizontal Scaling of Both Writes & Reads Without Sharding. Next, we dug into the details of the multi-patented ClustrixDB Rebalancer. This time we will discuss the ClustrixDB Query Evaluation Model. ClustrixDB is a […]

One of our founders had previously created a scale-out NoSQL database, and he was up for the challenge. Specifically, […]
