New-generation instances on AWS
We have added a new generation of instances on AWS, including ARM, AMD, and Intel-based options in all available regions. Our s2-series instance types, based on the c6a and m6a types, utilize AMD EPYC processors (codenamed Milan) and offer a 20-35% improvement in price performance compared to the previous generation. Similarly, our g2-series, which are ARM-based, now operate on c7g and m7g instance types, delivering a 25% boost in price performance compared to their predecessors.
Users currently using s1 or g1 types can continue doing so, but we strongly recommend you upgrade your instances. For those with high-availability configurations, this can be done with just a few clicks in the console without interrupting your services. More details about new instances can be found here.
New 23.12 version of ClickHouse available on DoubleCloud
To keep our commitment to offer the latest versions of ClickHouse, we are now supporting the newly released version 23.12 on DoubleCloud. My favorite feature in this update is the introduction of Refreshable Materialized Views. This feature enables you to schedule updates for the materialized view, supporting scenarios such as updating the view with fresh data from multiple tables or recreating a current snapshot of data. The complete changelog is available here.
Quality of life improvements
Here’s a list of some minor but potentially pivotal improvements that simplify workflows and day-to-day tasks:
The speed of cluster creation or changes has been significantly improved, now taking an average of 5-7 minutes compared to the previous 12 minutes.
We have also introduced additional charts in the Monitoring section for ClickHouse, including Disk IOPS and Disk Throughput. These metrics will assist in determining if your disk resources are sufficient for your workload.
Another enhancement is the ability to filter and search logs on the Logs page.
The ChatGPT model has been updated to support up to 128k tokens from 8k in AI insights.
Additionally, you can now easily select a source ClickHouse from the drop-down menu when creating a connection in the Visualization service, eliminating the need to provide connection strings.
