💡 The Analogy

The Orchestra (Conductor vs. Jam Session)

🧩 Consists of (The Parts)

Replication

Keeping a copy of the same data on multiple nodes.

Partitioning (Sharding)

Breaking a large dataset into smaller subsets (partitions) assigned to different nodes to enable unlimited horizontal scaling.

The Promises of Truth

Navigate the dangerous waters of distributed state, transactions, and consensus.

🎯 Mastery Criteria

✔
🤔 Reflection:
"Your database is too big for one disk and the read load is too high for one CPU. Design a topology using both Partitioning and Replication to solve this."
