Expand description

Type of a RowLayout

Variants

`Compact`

This type of layout will store each field with minimum bytes for space efficiency. Its typical use case represents a sorting payload that accesses all row fields as a unit.

`WordAligned`

This type of layout will store one 8-byte word per field for CPU-friendly, It is mainly used to represent the rows with frequently updated content, for example, grouping state for hash aggregation.
