The float8 data in the list vector and double array are both in a continuous memory region. So in theory, it is possible to populate the data in the `double[]` in a single copy. The unsafe API provides such functionality, and please note that: 1. There is some header space between the object address and the data address in the `double[]` 2. In the Arrow vector, there may be nulls in the slots, the behavior of such slots should be defined. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
