Since we are going to use envoy to contact MW applications servers I wonder if this kind of limits could be enforced by it? Today I think that wdqs updaters are talking to the edge caches and some requests might not reach app servers but when using envoy we will always hit the app servers. I have no clue what would be a reasonable limit here. I collected some stats on backend timings for the first 7 day of April 2021 (time_firstbyte on cache misses for `/wiki/Special:EntityData/QXYZ.ttl?flavor=dump&revion=XYZ`): | day of april | count | p50 | p75 | p95 | p99 | | 1 | 1241154 | 0.083 | 0.104 | 0.157 | 0.212 | | 2 | 1570675 | 0.084 | 0.105 | 0.156 | 0.210 | | 3 | 1315251 | 0.083 | 0.103 | 0.153 | 0.209 | | 4 | 1064852 | 0.081 | 0.102 | 0.155 | 0.209 | | 5 | 1232205 | 0.081 | 0.103 | 0.154 | 0.209 | | 6 | 1242875 | 0.082 | 0.103 | 0.156 | 0.209 | | 7 | 1257607 | 0.082 | 0.103 | 0.157 | 0.212 | TASK DETAIL https://phabricator.wikimedia.org/T275133 EMAIL PREFERENCES https://phabricator.wikimedia.org/settings/panel/emailpreferences/ To: dcausse Cc: dcausse, Gehel, Aklapper, Invadibot, MPhamWMF, maantietaja, wkandek, JMeybohm, CBogen, Akuckartz, Nandana, Namenlos314, jijiki, Lahi, Gq86, Lucas_Werkmeister_WMDE, GoranSMilovanovic, QZanden, EBjune, merbst, LawExplorer, _jensen, rosalieper, Scott_WUaS, Jonas, Xmlizer, jkroll, Wikidata-bugs, Jdouglas, aude, Tobias1984, Manybubbles, Addshore, Mbch331, Dzahn
