Partitioning by Hash of Key
Hashing the key to spread skewed data evenly — what a partitioning hash actually needs to be, why "consistent hashing" is the wrong name for it, and the range queries you give up to get the even distribution.

The Hot Key Hashing Can't Fix
Why a single very hot key defeats every partitioning scheme in this series, the random-suffix trick that splits it, and the read fan-out and bookkeeping you take on in exchange.
Why Partition at All
Why replication alone runs out of road, what a partition actually is under six different names, and why choosing how to partition is independent of choosing how to replicate.
Partitioning by Key Range
Assigning each partition a continuous span of the key space — why the boundaries have to follow the data, what it buys on range scans, and the hot spot a timestamp key walks straight into.
