At PromCon, Tom Wilkie from Grafana Labs outlined the future enhancements for Prometheus remote write, a protocol designed to send data from Prometheus to other systems. Key developments include improving metadata transmission, introducing exemplars, achieving atomicity in data transmission, better handling of 429 responses, and reducing bandwidth usage. The goal is to enhance standardization and interoperability among various vendors supporting remote write, ensuring a seamless user experience. Wilkie's team aims to address current challenges such as data loss during outages and the inefficiencies in bandwidth usage due to repetitive label transmission. These initiatives are part of a broader effort to make Prometheus remote write more reliable and efficient, facilitating global federation and integration with other systems.
