> In the UpsertCompiler#setValues() , if it's a local index, the key is prefixed with regionPrefix.
 During that process, ptr.get() is called to get the base key, and the code assumes the entire
array should be used.  However, if it's a variable length key, we could have trailing nulls
since the base key ptr array size is just an estimate.
