Deep Dive on ClickHouse Sharding and Replication

Deep Dive on ClickHouse Sharding and Replication

ClickHouse works out of the box on a single machine but gets complicated in a cluster. ClickHouse provides two scaling-out dimensions — sharding and replication — and understanding when and how those should be applied is vital for production and high-load applications. In this webinar we will focus on ClickHouse cluster setup and configuration, cluster operation in public clouds, executing distributed queries, hedged requests, and more

Eureka! 8 developer tricks for running ClickHouse on Kubernetes

Eureka! 8 developer tricks for running ClickHouse on Kubernetes

Kubernetes is a great platform for ClickHouse with many success stories.
What are the tricks that make it possible?
This webinar shows 8 practices to help ClickHouse developers build faster and more cost-efficient analytics on Kubernetes. We’ll start with using the Altinity operator, work our way through various techniques to scale up or shut off compute, and end with advice on zero-downtime upgrade. Along the way, we’ll review key Kubernetes features like node autoscaling.
Watch it to learn more about data on Kubernetes and impress your friends!

Using Kubernetes Secrets and Environment Variables in Altinity.Cloud

Using Kubernetes Secrets and Environment Variables in Altinity.Cloud

Configuring ClickHouse often involves authentication tokens, credentials, and other sensitive information. Altinity.Cloud has great integration with Kubernetes Secrets and environment variables. In this post we’ll show how easy it is to use the Altinity Cloud Manager (ACM) to integrate the Kubernetes Secrets in your VPC with your ClickHouse configuration.

FOSDEM 2024

FOSDEM 2024

FOSDEM was a free event for software developers to meet, share ideas, and collaborate. Every year, thousands of developers of free and open-source software from all over the world gather at the event in Brussels. Our CEO, Robert Hodges was one of the speakers at this conference and his talk revealed all on Monitoring & Observability Devroom on the 4th of February. The FOSDEM event is a free and non-commercial conference organized by the community for the community. The goal is to provide free and open-source software developers and communities a place to meet to get in touch with other developers and projects.

ClickHouse and Apache Parquet: Past, Present, and Future

ClickHouse and Apache Parquet: Past, Present, and Future

Apache Parquet, a popular columnar storage format, has become a linchpin for data-driven organizations seeking efficient and scalable solutions.
ClickHouse can read and write Parquet data at very high speeds which allows interesting integration capability.
In this webinar, we will walk through the existing ClickHouse functionality, give an overview of performance improvements over the last year, and discuss how ClickHouse can do even better.

2023++

2023++

2023 is almost over. In 2023, it took Altinity plenty of running to keep up the momentum, and we managed to run even faster to discover more opportunities for our users and ourselves.

Let’s take a look back and see what happened during our 2023 run, and what we expect in 2024.

Uniting Open Source and Modern Data Stack at OSA CON 2023

Uniting Open Source and Modern Data Stack at OSA CON 2023

OSA CON 2023 brought together creators and users from across the open source analytic community to explore open source, modern data stacks. Dozens of great talks from 53 presenters are now at your fingertips!

Is It Safe? Security Hardening for Databases Using Kubernetes Operators – Robert Hodges, Altinity – KubeCon | CloudNativeCon North America 2023

Is It Safe? Security Hardening for Databases Using Kubernetes Operators – Robert Hodges, Altinity – KubeCon | CloudNativeCon North America 2023

Thanks to the Operator Pattern, Kubernetes is now an outstanding platform to run databases. But to quote Marathon Man, “Is it safe?” This talk is a top-level review of the database security problem in Kubernetes, standard ways that operators can mitigate threats, and a wallet-sized checklist of security features you should look for in any operator you use. Our talk is practical and focused on the needs of Kubernetes developers. Enjoy it now!

Data on Kubernetes Operator Maturity- Melissa Logan, Michelle Au, Robert Hodges & Gabriele Bartolini – KubeCon | CloudNativeCon North America 2023

Data on Kubernetes Operator Maturity- Melissa Logan, Michelle Au, Robert Hodges & Gabriele Bartolini – KubeCon | CloudNativeCon North America 2023

Panelists from the Data on Kubernetes Community Operator SIG and CNCF projects will discuss key features of Kubernetes database operators — what works, what doesn’t, and where the industry is going. Panelists will also present an overview of collaborative projects between the Dat on Kubernetes Operator SIG, CNCF Storage TAG, App SIG, Security SIG and others.
