Uhm, no. Data warehouse is not a database with operational (i.e. current) data, it's a database with historical data. If it is out of sync with production for a day or a week, it's totally OK, depending on its design.

So no, cache invalidation is not a solved problem there.

I've worked with data warehouses which were replicated like a multimaster, YMMV.

dozzie, could you remove the "Uhm, no." from that? It only adds snark to an otherwise good comment.
