Hi,
I'm proposing a new community module, a datastore that would read a MBtiles
filled with vector
tiles, described with the "json" metadata field [1], and would allow to
consume it as vector data.
If multiple layers are present, they would be presented as separate feature
types, though maybe we could
add later an option to have a mixed type feature source too (not sure how
well that would work).
The store would read and stitch back together features from the tiles,
using the maximum zoom level
available if there are no hints, and lower zoom levels if the geometry
distance hints are provided.

Cheers
Andrea

for "json" in the Metadata section)
