ClickHouse Releases: Upgrade or not Upgrade

ClickHouse Releases: Upgrade or not Upgrade

ClickHouse team has released 1.1.54385 version recently. This is yet another bugfixing update in a row of small updates that followed 1.1.54378 release from mid-April. Unfortunately, ClickHouse test coverage is not perfect, and sometimes new features are accompanied by disappointing regressions. ClickHouse team certainly addresses problems in hotfix releases, but ClickHouse streamlined release version numbering makes it not easy to distinguish hotfixes from the feature releases. So how to decide is it safe to upgrade or not?

ClickHouse release 1.1.54380

ClickHouse team and community contributors actively develop ClickHouse adding many new features, improving performance and flexibility. Unfortunately, sometimes it affects stability of the product. We were very upset by some unexpected regressions in recent ClickHouse releases. After initial testing of latest 1.1.54380 version we think it may be a good candidate for the new stable release. Previous releases free from severe issues were aged 1.1.54292 and 1.1.54327.

ClickHouse 1.1.54380 is available in Yandex and Altinity repositories. So what’s new and important in 1.1.54380 and previous release 1.1.54378.

ClickHouse for Machine Learning

ClickHouse for Machine Learning

Jan 18, 2018
ClickHouse is very flexible and can be used for various use cases. One of the most interesting technology areas now is machine learning, and ClickHouse fits nicely there as very fast datasource. A few months ago ClickHouse team implemented the support for ML algorithms, that makes it much easier and faster to run ML over ClickHouse data. They started with open source Yandex CatBoost algorithm, but it can be extended with other algorithms in the future. In this article, we posted a tutorial on how ClickHouse can be used to run CatBoost models.
