Grafana Cloud has introduced a full trace retention search feature in beta for its Grafana Cloud Traces, extending the capabilities of recent trace searches to a 30-day retention period across all Google Cloud Platform-based clusters in the U.S., Europe, and Australia. This enhancement is built on serverless technologies, allowing rapid data scanning by deploying hundreds of Google Cloud Functions, although the search is limited to a maximum of 24 hours at a time. Currently, the search throughput ranges from 30 GB/s to 60 GB/s, but efforts are underway to further optimize this by potentially adopting new data storage methods like columnar formats. Despite being in beta, the feature aims to solidify Tempo's position as a leading distributed tracing backend, with further innovations planned in metrics generation. Users can engage with the Grafana Labs community for updates and support, while those new to Grafana Cloud are encouraged to explore its offerings, including a free tier for metrics, logs, traces, and dashboards.
