Scuba (Meta)¶
Scuba is Meta's warm / real-time data store — optimised for interactive slice-and-dice analytics on recent operational data. Stub page on this wiki; cited by name in the 2024-12-02 cryptographic monitoring post. The public Scuba reference is the 2013 Scuba: Diving into Data at Facebook paper.
Role for this wiki¶
- Warm tier downstream of Scribe: ingested events land in Scuba for real-time analysis and dashboarding.
- Warm tier + the cold tier together: Scuba for short-term, Hive for long-term, forming Meta's two-tier telemetry storage pattern.
- Not a warehouse. Per the 2024-12-02 post, Scuba is "optimized to be performant for real-time data (i.e., warm storage) and can be inefficient if used for larger datasets" — the cost motivation for tiering large long-retention datasets into Hive.
Seen in¶
- sources/2024-12-02-meta-built-large-scale-cryptographic-monitoring — Scuba is the warm destination for FBCrypto's aggregated counts; post discloses "occasionally put an increased load on Scuba" alongside Scribe as a named capacity-management challenge.
