Episode notes
How Russell Landed On Iceberg
- Russell joined Apple's data tables team after interviewing for Spark and was persuaded to work on Apache Iceberg.
- He helped convince Apple teams to migrate from bespoke table systems to Iceberg to reduce operational burden.
Offload Table Complexity
- Offload table-format complexity to shared teams or managed services where possible.
- Avoid building bespoke compaction, locking, and file-management systems unless core to your business.
Apache's Community-First Governance
- Apache projects transfer authority to a community rather than a single company.
- PMC membership grants operational control that persists regardless of company changes.
