ClickHouse now attempts to connect to every resolved IP address when accessing an S3 proxy, improving connection reliability.
Why it matters
This feature addresses the issue where S3 proxies (primarily used in Yandex Cloud) may have multiple IP addresses but only one was tried previously. By trying all resolved IPs, ClickHouse increases the chance of successfully connecting to S3 proxies, enhancing robustness and availability for users relying on these proxies.How to use it
The new behavior is applied automatically when connecting through S3 proxies. No explicit user action or configuration is required to enable this feature; ClickHouse will internally try all resolved IP addresses for the given S3 proxy endpoint.
