@ -1877,7 +1877,7 @@ This release contains bug fixes for the previous release 1.1.54276:
- cleanup_delay_period sets how often to start cleanup to remove outdated data.
- replicated_can_become_leader can prevent a replica from becoming the leader (and assigning merges).
* Accelerated cleanup to remove outdated data from ZooKeeper.
* Multiple improvements and fixes for clustered DDL queries. Of particular interest is the new setting distributed_ddl_task_timeout, which limits the time to wait for a response from the servers in the cluster.
* Multiple improvements and fixes for clustered DDL queries. Of particular interest is the new setting distributed_ddl_task_timeout, which limits the time to wait for a response from the servers in the cluster. If a ddl request has not been performed on all hosts, a response will contain a timeout error and a request will be executed in an async mode.
* Improved display of stack traces in the server logs.
* Added the "none" value for the compression method.
* You can use multiple dictionaries_config sections in config.xml.

* Ускорена очистка неактуальных данных из ZooKeeper

* Множественные улучшения и исправления работы кластерных DDL запросов. В частности, добавлена настройка distributed_ddl_task_timeout, ограничивающая время ожидания ответов серверов кластера. Если запрос не успел выполниться на всех нодах в установленное время, ответ будет содержать timeout ошибку и дальнейшее выполнение этого запроса будет происходить в асинхронном режиме
* Улучшено отображение стэктрейсов в логах сервера
* Добавлен метод сжатия none
* Возможность использования нескольких секций dictionaries_config в config.xml
