September 2026 Summaries

Dash0 has joined the Agentic AI Foundation as a Silver member to support open standards for the rapidly developing agentic AI ecosystem, including protocols such as MCP. The company emphasizes its existing commitment to nonproprietary technologies through its use of OpenTelemetry, PromQL, Perses, open-source telemetry plugins, OTelBin, and its acquisition of Polar Signals, the team behind Parca. Dash0 plans to contribute particularly to the AAIF Observability & Traceability working group, where it sees overlap between emerging agent protocols and OpenTelemetry’s generative AI observability efforts. Its focus includes developing consistent ways to describe agent behavior, tool usage, objectives, and complete agent runs without fragmented vendor-specific formats, and it invites practitioners building or instrumenting agents to participate in the working group’s open discussions.

A production ClickHouse cluster was upgraded from AWS Graviton 4 m8g.48xlarge instances to same-sized Graviton 5 m9g.48xlarge instances, retaining identical CPU count, memory, storage, software, data structures, and Keeper configuration to isolate hardware effects. Although the new instances cost 9% more per hour, a before-and-after analysis of comparable weekday workloads, standardized by query type and baseline traffic mix, found that they used about 23% less cluster CPU and reduced CPU consumption per byte by 21% for reads, 28% for writes, and 33% for asynchronous insert flushing. Overall SELECT latency improved substantially despite a 17% increase in query volume, with median latency falling 48% and p95, p99, and p99.9 latency improving by roughly 59–63%; background merge throughput also rose 41%, while slow merges became 29% faster. The higher hourly price therefore translated to lower effective cost per unit of work, estimated at 13.9% cheaper for reads, 21.3% cheaper for inserts, and 15.8% cheaper on average cluster CPU usage. Broader adoption is currently constrained by regional availability of Graviton 5 instances and the absence of memory-optimized r9g types.
