GenerateUnsafeRowJoiner

object GenerateUnsafeRowJoiner extends CodeGenerator[(StructType, StructType), UnsafeRowJoiner]

A code generator for concatenating two UnsafeRows into a single UnsafeRow.

The high level algorithm is:

1. Concatenate the two bitsets together into a single one, taking padding into account. 2. Move fixed-length data. 3. Move variable-length data. 4. Update the offset position (i.e. the upper 32 bits in the fixed length part) for all variable-length data.
