Optimistically create ZooKeeper ancestor nodes to improve reliability and performance during metadata operations.
Why it matters
This feature addresses the problem of ensuring that all necessary parent znodes exist in ZooKeeper before creating or modifying child nodes, while avoiding race conditions and redundant checks. It enhances the stability and efficiency of ZooKeeper-based metadata handling in ClickHouse.How to use it
The creation of ZooKeeper ancestor nodes is handled optimistically by default within ClickHouse's internal ZooKeeper interactions. No additional user configuration is required to enable this behavior.
