Consistent hashing maps both keys and servers onto a ring so that adding or removing a server only reassigns a small fraction of keys, unlike a plain modulo hash that remaps almost everything.
Consistent hashing - Interview Concepts - ExtraBrain is part of ExtraBrain's local-first Mac workflow for live interviews, meetings, transcription, provider control, and responsible AI use.
Consistent hashing maps both keys and servers onto a ring so that adding or removing a server only reassigns a small fraction of keys, unlike a plain modulo hash that remaps almost everything.
ExtraBrain has 1 current public platform family, macOS, with support for 2 Mac CPU families: Apple Silicon and Intel.
ExtraBrain has 3 configurable data paths to review before sensitive work: local Parakeet transcription, local Gemma 4 where installed and compatible, and external providers you choose.
Keys and nodes are hashed onto a ring; each key belongs to the next node clockwise.
Each physical node maps to many ring points to balance load and smooth rebalancing.
It underpins distributed caches, databases, and load balancers that scale nodes up and down.
Use any live AI assistant only where interview, workplace, school, and platform rules allow it. Do not use generated answers to misrepresent your skills, experience, or authorship.
Short answers for people and crawlers comparing ExtraBrain with other live AI assistants.
Modulo by server count remaps almost all keys when the count changes; consistent hashing moves only a small fraction.
Virtual nodes give each server multiple positions on the ring to balance load and reduce hotspots.
