Add support for specifying extra Keeper ACL
Add support for specifying extra Keeper ACL for paths in config. If you want to add extra ACL for a specific path you define it in the config under zookeeper.path_acls. #82898 (Antonio Andelic).Why it matters
This feature allows users to define additional access control lists (ACLs) for particular ZooKeeper paths, providing finer-grained security and access management. It helps in customizing permissions for different parts of the ZooKeeper hierarchy used by ClickHouse internally.How to use it
To use this feature, add the desired extra ACL entries under thezookeeper.path_acls section in the ClickHouse configuration file. Define the specific paths and their associated ACLs to apply custom access rules.
