Developed and delivered HTTP transport concurrency limiting for the ClickHouse/clickhouse-go repository, introducing a configurable option to restrict the maximum number of concurrent HTTP connections per host. This feature was implemented by integrating a MaxConnsPerHost limit into the existing http.Transport configuration, allowing for more controlled resource utilization and preventing excessive connections to individual hosts. The approach focused on minimal disruption to the codebase while enhancing stability and predictability under high-load conditions. Leveraging Go, net/http, and concurrency control techniques, the work improved scalability and reliability for production deployments, supporting more efficient capacity planning and reducing the risk of connection storms.
