Eric Anderson (@ericmander) returns to Temporal with co-founder Maxim Fateev (@mfateev) and principal engineer Dominik Tornow (@DominikTornow). When Maxim joined us in September of 2020, the company called their project a “workflow orchestrator.” Today, Temporal has grown in popularity and usability, but the terminology around that abstraction has changed. Tune in to track the evolution of what Maxim calls a genuinely “new category of software.” In this episode we discuss: New features and developments in the last 2 years The proper way to pronounce “Temporal” How Temporal guarantees that workflow execution actually runs to execution Describing Temporal as a new pair of glasses Replay, Temporal’s first developer conference on August 25-26, in Seattle Links: Temporal Cadence Apache Cassandra Replay People mentioned: Samar Abbas (@samarabbas77) Other episodes: Temporal with Maxim Fateev Apache Cassandra with Patrick McFadin
