Understanding How YugaByte DB Runs on Kubernetes

As we reviewed in “Docker, Kubernetes and the Rise of Cloud Native Databases”, Kubernetes has benefited from rapid adoption to become the de-facto choice for container orchestration. This has happened in a short span of only 4 years since Google open sourced the project in 2014. YugaByte DB’s automated sharding and strongly consistent replication architecture lends itself extremely well to containerized deployments powered by Kubernetes orchestration.

Benchmarking an 18 Terabyte YugaByte DB Cluster with High Density Data Nodes

For ever-growing data workloads such as time series metrics and IoT sensor events, running a highly dense database cluster where each node stores terabytes of data makes perfect sense from a cost efficiency standpoint. If we are spinning up new data nodes only to get more storage-per-node, then there is a significant wastage of expensive compute resources. However, running multi-terabyte data nodes with Apache Cassandra as well as other Cassandra-compatible databases (such as DataStax Enterprise) is not an option.

Getting Started With YugaByte DB on Pivotal Container Service (PKS)

Pivotal Container Service (PKS) simplifies the deployment and management of enterprise-grade Kubernetes on both public and private clouds. The PKS APIs and its command line interface make it easy to create and manage Kubernetes clusters without cloud-vendor lock in.

Getting started with PKS is easy

Apache Cassandra Architecture Fundamentals

What is Apache Cassandra?

Apache Cassandra is a distributed open source database that can be referred to as a “NoSQL database” or a “wide column store.” Cassandra was originally developed at Facebook to power its “Inbox” feature and was released as an open source project in 2008. Cassandra is designed to handle “big data” workloads by distributing data,

How Does the Raft Consensus-Based Replication Protocol Work in YugaByte DB?

As we saw in ”How Does Consensus-Based Replication Work in Distributed Databases?”, Raft has become the consensus replication algorithm of choice when it comes to building resilient, strongly consistent systems. The YugaByte DB database uses Raft for both leader election and data replication. Instead of having a single Raft group for the entire dataset in the cluster,

$16 Million Funding Round

In case you missed the news earlier this Summer, YugaByte raised an additional $16M of funding from Dell Technologies Capital and our previous investor Lightspeed Venture Partners. With the additional funding, we are accelerating investments in engineering, sales, and customer success to scale our support for enterprises building business-critical applications in the cloud.

How Does Consensus-Based Replication Work in Distributed Databases?

Whether it be a WordPress website’s MySQL backend or Dropbox’s multi-exabyte storage system, data replication is at the heart of making data durable and available in the presence of hardware failures such as machine crashes, disk failures, network partitions and clock skews. The basic idea behind replication is very simple: keep multiple copies of data on physically isolated hardware so that the failure in one does not impact the others and as a result,

A Quick Guide to Secondary Indexes in YugaByte DB

When creating a Cassandra-compatible YCQL table in YugaByte DB, you are required to create a primary key consisting of one or more columns of the table. Primary key based retrievals are efficient because YugaByte DB automatically indexes/organizes the data by the primary key. However, there are many use-cases where you may need to retrieve data using columns that are not a part of the primary key.

Implementing Distributed Transactions the Google Way: Percolator vs. Spanner

Our post 6 Signs You Might be Misunderstanding ACID Transactions in Distributed Databases describes the key challenges involved in building high performance distributed transactions. Multiple open source ACID-compliant distributed databases have started building such transactions by taking inspiration from research papers published by Google. In this post, we dive deeper into Percolator and Spanner, the two Google systems behind those papers,
