Clustering interview questions

1. A.horizontally partitioning the keyspace across multiple primary nodes so each holds only a subset of the data
2. B.one of 16384 buckets to which every key is mapped, determining which node in a sharded deployment owns that key
3. C.a substring enclosed in braces within a key that forces related keys into the same bucket so multi-key operations work
4. D.migrating ownership of buckets between nodes to rebalance load or accommodate added or removed members

Answer + AI explanation with Pro
