Module value_encoding

Expand description

Value encoding is an encoding format which converts the data into a binary form (not memcomparable, i.e., Key encoding).

Modules§

column_aware_row_encoding: Column-aware row encoding is an encoding format which converts row into a binary form that remains explanable after schema changes Current design of flag just contains 1 meaningful information: the 2 LSBs represents the size of offsets: u8/u16/u32 We have a Serializer and a Deserializer for each schema of Row, which can be reused until schema changes
