Description

Hi !
I want to encode sorted timestamps using delta of delta, which in go, i find delta_bit_packing.go seems to support. But i can not find related java code. So it is not support in java, or can not specify delta encode int64 explicitly ?

Research direction

Start by reading the referenced delta_bit_packing.go implementation and locating the corresponding Java encoding code in Apache Arrow. Determine whether Java can explicitly apply delta-of-delta encoding to int64 timestamps, then identify or add coverage for Java-to-Go compatibility. Done means the supported behavior and its cross-language validation are clear.
