I'm curious what solutions there may be for generating Mapbox vector tiles from SDO_Geometry data? There doesn't appear to be native support as with PostGIS.
Some alternatives which should work:
1) Use GeoServer vector tile output http://docs.geoserver.org/latest/en/user/extensions/vectortiles/index.html with Oracle datastore http://docs.geoserver.org/latest/en/user/data/database/oracle.html
2) Use MapServer vector tile output http://mapserver.org/development/rfc/ms-rfc-119.html with Oracle Spatial input http://www.mapserver.org/input/vector/oracle.html
3) Read data from Oracle with PostgreSQL by using the GDAL/OGR foreign data wrapper https://wiki.postgresql.org/wiki/Foreign_data_wrappers and let PostGIS do the rest.
