Wait, does that mean that the current query service actually gives each query a consistent view of the database for up to 60 seconds? I always assumed that WDQS didn’t give you the same transactionality guarantees as e. g. MySQL, because how could that possibly work with such a high query and update rate… Cheers, Lucas _______________________________________________ Wikidata mailing list Wikidata@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikidata
