In March 2025, Alex Salt developed HTTP transport concurrency limiting for the ClickHouse/clickhouse-go repository. He introduced a configurable option to restrict the maximum number of concurrent HTTP connections per host, integrating this feature directly into the http.Transport configuration. Using Go and leveraging the net/http package, Alex focused on backend development and network programming to address resource utilization and prevent excessive connections to a single host. This solution improved stability and predictability under high-load conditions, supporting scalable client deployments. The work demonstrated careful integration with minimal disruption, resulting in enhanced reliability and more manageable capacity planning for production environments.
