Grafana Tempo 2.4 introduces several key features and enhancements aimed at boosting performance and operational capabilities, including the experimental TraceQL metrics feature, which allows for creating metrics from traces and supports adhoc aggregation using TraceQL queries. This release also brings tiered caching with a simplified configuration that improves cache management and monitoring, as well as TCO improvements by reducing unnecessary backend polling. Additionally, Tempo now supports cross-tenant queries, making it easier to run queries across multiple tenants in multi-tenant modes, and vParquet3 is set as the default storage backend. Future developments focus on expanding TraceQL metrics capabilities and gRPC streaming support, with ongoing efforts to enhance the TraceQL language. The release encourages community engagement through various platforms and invites users to explore opportunities at Grafana Labs, while also promoting the Grafana Cloud free tier for getting started with Tempo.
