  • Code Europe 2026 Talk – Magical Mystery Tour: A Roundup of Observability Datastores

    The telemetry storage landscape is crowded, and picking the right datastore is rarely obvious. In "Magical Mystery Tour: A Roundup of Observability Datastores," Josh Lee walks through the foundations of metrics, traces, logs, profiles, and wide events, then weighs the strengths and limits of Postgres, OpenSearch, Prometheus, Cassandra, the LGTM stack, ClickHouse®, and VictoriaMetrics for each job. Whether you are building an observability stack from scratch or tuning one you already run, you will leave with a clearer view of the trade-offs.

  • ATO 2026 – All Things Open 2026 – Observability is Broken and Open-Source (will be) the Solution

    The observability industry was built on a simple trade: ship your telemetry to a vendor and get insights back. That bargain made sense when data was small and cheap. It is not anymore. Josh Lee, Open Source Advocate at Altinity, argues that OpenTelemetry solved instrumentation and portability, but observability cannot be truly open until the storage layer is open, standardized, and hostable anywhere.
