Keeping Your Cloud Native Data Safe: A Common-Sense Guide to Kubernetes, ClickHouse, and Security
Kubernetes is now the default environment for ClickHouse-based analytic platforms. But how to keep your data safe? Our talk is a practical walkthrough of security for ClickHouse on Kubernetes. We'll show you how to divide the security problem into easily understood pieces. Then we'll walk through practical ways you can protect data using the Altinity Operator for ClickHouse, Kubernetes Secrets, managed Kubernetes, and more. You don't have to be a security wizard to protect your ClickHouse data. Common sense and a little organization will do. Join us to find out how!
API World 2023 – Live Event
Oct 24-26, 2023 · Santa Clara, CA, · Virtual Join thousands of global technical leaders, engineers, software architects, and executives at the world’s largest and longest-running API & microservices event – in its 11th year! Our CEO, Robert Hodges, will be speaking about Building Real-time Analytics on Kubernetes with the ClickHouse Operator. If you are looking to transform your apps with real-time analytics, Kubernetes is an outstanding platform operating high-performance databases and ClickHouse runs well on it. This talk starts from the basics of Kubernetes and introduces an operator we implemented that enables you to stand up ClickHouse clusters. We'll walk through the installation process and bring up a ClickHouse cluster in real time during the talk. We'll then show how running on Kubernetes enables emergent behavior like independent scaling of compute and storage, server fault tolerance, cross-AZ high availability, and rolling upgrades. You'll have enough guidance from this talk to start your journey to real-time data on a robust, cloud-native architecture.
Safety First! Using clickhouse-backup for ClickHouse Backup and Restore
Backups protect ClickHouse data in cases ranging from accidentally dropping a database to data centers burning down. In this webinar, we'll compare available backup options for ClickHouse, then zero in on clickhouse-backup, a popular open-source project that Altinity maintains. The presentation will discuss how clickhouse-backup works, standard backup and restore commands, and tips for reliable operation in production systems. We'll end with Q & A. Join us if you love your ClickHouse data and want to ensure it sticks around!

ClickHouse Data Management Internals — Understanding MergeTree Storage, Merges, and Replication
ClickHouse manages huge amounts of data in MergeTree tables. But how is MergeTree organized in storage? What's a merge and how does it work? How does ClickHouse replicate data and commands across clusters? And what's a mutation? Our talk explains these features and more. We'll even discuss mysteries like hard links and the DDL replication queue. Our answers focus on the knowledge necessary to run ClickHouse efficiently and avoid problems. Bring your curiosity and questions!
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.
Presenter: Alexander Zaitsev - Altinity co-founder and CTO. ClickHouse® expert since 2016
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. Join us to learn more about data on Kubernetes and impress your friends!
Deep Dive on ClickHouse® Sharding and Replication Webinar
ClickHouse® works out of the box on a single machine, but it 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.
ClickHouse® Performance Master Class – Tools and Techniques to Speed up any ClickHouse® App Webinar
ClickHouse® gives impressive performance out of the box. Our webinar will show you how to make it amazing. We start by providing a framework for performance that includes basic drivers like I/O and compute, as well as ClickHouse® structures like compression and indexes. We'll also discuss tools to evaluate performance including ClickHouse® system tables and EXPLAIN. We'll then demonstrate how to evaluate and improve performance for common query use cases ranging from MergeTree data on block storage to Parquet files in data lakes. Join our webinar to become a master at diagnosing query bottlenecks and curing them quickly.
Petabyte-Scale Data in Real-Time: ClickHouse®, S3 Object Storage, and Data Lakes
These days new ClickHouse® applications start with petabyte-sized datasets and scale up from there. Fortunately, ClickHouse® gives you open-source tools for real-time analytics on big data: MergeTree backed by object storage as well as reading on data lakes. We'll start by showing you popular design patterns for ingest, aggregation, and queries on source data. We'll then dig into specific best practices for defining S3 storage policies, reading from Parquet data, backing up, monitoring, and setting up high-performance clusters in the cloud. It's all open source and works in any cloud. Join us!
