Space consumption of each child dataset snapshot after zfs snapshot -r

after performing zfs snapshot -r zpool@myRecursiveSnapshot

will, for example, the zpool/usr@myRecursiveSnapshot and zpool/var@myRecursiveSnapshot snapshots take up space in addition to zpool@myRecursiveSnapshot?

Yes. A recursive snapshot creates a snapshot in the child filesystems in the same way that it would if you took a snapshot of each child filesystem separately.

Initially, the snapshot consumes very little additional space. As the filesystems change, however, the snapshots consume more space because the original data must also be stored to maintain the snapshot.
