TASK DESCRIPTION As a maintainer of the rdf-streaming-updater I want information to be logged when divergences are detected on patch application so that I can more easily debug the cause of these divergences. When applying a RDF patch to the triple store (blazegraph) some divergences may occur for the following reasons: - the state of the store is not what is expected by the flink pipeline (actual divergences) - false positives: some triples/literals are modified on the fly by blazegraph (unicode normalization/large values cutoff/precisions). Should be a couple to a dozen triples per hour. Finding out what's the cause of a non-negligible bump in the number of divergences is not straightforward today, adding some more logs to the streaming consumer will help such investigations. AC: - meaningful logs allowing to trace what are the changes involved in a bump of divergences TASK DETAIL https://phabricator.wikimedia.org/T277443 EMAIL PREFERENCES https://phabricator.wikimedia.org/settings/panel/emailpreferences/ To: dcausse Cc: Aklapper, dcausse, MPhamWMF, maantietaja, CBogen, Akuckartz, Nandana, Namenlos314, Lahi, Gq86, Lucas_Werkmeister_WMDE, GoranSMilovanovic, QZanden, EBjune, merbst, LawExplorer, _jensen, rosalieper, Scott_WUaS, Jonas, Xmlizer, abian, jkroll, Wikidata-bugs, Jdouglas, aude, Tobias1984, Manybubbles, Mbch331
