> 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.
