Grafana Tempo 2.3 introduces a new storage format, vParquet3, which includes dedicated attribute columns to enhance TraceQL query performance. These columns offer significant improvements in query speed and resource utilization by storing high-cardinality attributes separately, thereby reducing memory usage and increasing efficiency. The feature allows users to configure up to 10 string attributes at the resource and span levels, which are then stored in dedicated columns. This configuration should be approached strategically, either by analyzing data patterns or query usage, and is not meant to be frequently changed due to the creation of new shards in the block space. Real-world tests have shown notable reductions in query tail latency and resource consumption, with memory and CPU usage dropping significantly. Future updates may include automated configuration generation to accommodate multiple tenants and ease the setup process.
