Is there opensource data pipeline which can be used?

We currently have different open source components like for

Tile server->https://github.com/TileStache/TileStache,https://osm2pgsql.org/

Styling and rendering->https://github.com/mapbox/mapbox-gl-js

OSM to Postgres conversion-https://osm2pgsql.org/

All of the above components can be used to create one time MAP from country files.

My question is targeted to that, do we have any opensource component which can listen to deltas(which can be within an country) an keep on updating vectors tiles in cache?

If we have this there can be a full opensource suite which can be used for end-to-end map creation which all is driven by community.

Not vector tiles, but https://switch2osm.org/serving-tiles/ is “a full opensource suite which can be used for end-to-end map creation which all is driven by community.”. https://switch2osm.org/serving-tiles/updating-as-people-edit/ describes an “opensource component which can listen to deltas”.

The only Vector Tile implementation that I know of that supports updates is OsmAnd Live, but I’m no expert on such things.
