My point is let's leave a place for it? At the moment we can have a dummy
placeholders.
And even for simple traversal queries! For example, in the graph `people
likes movies`, if I want to do something `MATCH (:people {id: [1, 2, 3]} ->
[likes] -> (:movies {name: [Termninator, Matrx]} return people`, it is
definitely not a bad idea to skip all the chunks from `poople` that does not
contains vertices with id `1, 2, 3`. The same is true for edges `likes`: we can
simply skip most of parquet chunks and read to memory only chunks, related to
edges, that starts from `1, 2, 3`
etc.
Otherwise we may read to memory millions of nodes and billions of edges just
to scan them and filter out most of them...
