Thanks brian, but in C can you append a view to another ?
I did not find any append in C api for view.
I found "concat" but this function does not copy data :
doc of Concat() : <<<This operation is a bit similar to appending all rows from the second
view, but it does not actually store the result anywhere, it just looks like it.>>>
