Algorithms

The architect's toolbox - the specific computational techniques that show up inside real systems. Not LeetCode; these are the building blocks you need to recognize when reading a case study or designing one.

Planned:

• Consistent hashing
• Bloom filter · Counting bloom
• HyperLogLog (cardinality) · Count-min sketch (frequency)
• Merkle trees (anti-entropy, verification)
• CRDTs (conflict-free replicated data types)
• Vector clocks / Lamport timestamps
• Raft / Paxos (consensus) - theory in ../foundations/distributed-systems
• Gossip / SWIM (membership)
• Token bucket vs leaky bucket (rate limiting)
• LSM-tree vs B-tree
• Quorum (R + W > N)
• Geohashing / H3
• Reservoir sampling
