Vertical Partitioning
A partitioning strategy that separates columns or related attribute groups of a logical record into different physical structures.
Technical Context
It can keep hot narrow columns close to frequent access paths while moving large or rarely used attributes elsewhere. The trade-off is extra joins or lookups, more complex consistency boundaries, and possible write amplification when logically related fields change together.
