New Altinity Stable ClickHouse 19.11.8 Release Is Out!

New Altinity Stable ClickHouse 19.11.8 Release Is Out!

It has been quite a while since we announced the previous ‘Altinity Stable’ ClickHouse in December 2018. Since then there have been a lot of changes and new features in ClickHouse. The core team has merged almost 1000 pull requests, and 217 contributors completed about 6000 commits. Unfortunately, during those months of active development ClickHouse suffered from stability issues. We have been working hard together with the core ClickHouse team to nail them down. Today we are happy to introduce a new ‘Altinity Stable’ release 19.11.8!

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.
