Explore the concept of delta temporality in OpenTelemetry and its broader applications in this informative conference talk. Delve into the OpenTelemetry specification for metrics data model, examining the two distinct types of temporality: cumulative and delta. Understand the current default setting of cumulative temporality in the metrics SDK specification and the option for users to switch to delta temporality. Investigate the use cases, advantages, and potential pitfalls of employing delta temporality in OpenTelemetry. Compare the two temporality types, highlighting scenarios where delta temporality proves beneficial. Examine the implementation of delta temporality beyond the SDK, focusing on its utilization in various components of the OpenTelemetry Collector. Gain insights from speakers Matej Gera and Oded David as they discuss the historical background, practical applications, and considerations for working with delta temporality in cloud-native environments.
