Big Tent hosts Mat Ryer and Tom Wilkie talk with Marco Pracucci (Grafana Labs), Cyril Tovena (Grafana Labs), and Ryan Worl (WarpStream/Confluent) about building Sigyn (the internal code name for Mimir’s next-gen architecture), public, open source, and designed for lower TCO and stronger reliability. They cover gapless consumption, predictable partitioning, new “block builder” components, and the practical realities of migrating “mid-flight.”
