Configerator (Meta)

Configerator is Meta's holistic configuration management system — the canonical mechanism by which configuration is authored, versioned, reviewed, distributed, and rolled out across Meta's fleet. Public paper: "Holistic configuration management at Facebook" (Meta Research; SOSP 2015).

This wiki page is a stub — the 2025-01-21 Strobelight post uses Configerator as a given without redocumenting it.

Role on this wiki

• The configuration substrate through which Meta engineers enable continuous or triggered profiling of their services under Strobelight. A service owner commits an override such as add_continuous_override_for_offcpu_data(team, Type.SERVICE_ID, service_name, samples_per_hour) into Configerator; Strobelight picks it up fleet-wide.
• Canonical Meta "config as code, committed and rolled out via Configerator" disclosure — surfacing a foundational Meta primitive that earlier Meta posts (Sigma / Haskell, Sapling, FBCrypto) referenced only obliquely.
