Allows using IP addresses alongside hostnames to identify servers when executing clustered DDL queries in ClickHouse.
Why it matters
This feature was created to enhance the flexibility and reliability of server identification in clustered DDL queries. It solves problems related to hostname resolution issues or when servers are better identified by their IP addresses. It provides value by allowing more robust and precise targeting of servers in a ClickHouse cluster during DDL operations.How to use it
When configuring clustered DDL queries, specify servers using their IP addresses in addition to or instead of hostnames. This enables ClickHouse to recognize and route DDL queries properly to the intended nodes using IP-based identification.
