TASK DESCRIPTION As a PM/tech lead for WDQS, I want to know what are the different and best options are for moving WDQS off of Blazegraph, so that I can decide which option to move forward with in scaling up WDQS beyond Blazegraph's current capabilities. Blazegraph is unmaintained and is reaching/has reached its limits for handling the scale of Wikidata and the volume/complexity of queries to it, causing a number of current problems and making future catastrophic failures probable. It is very likely/desirable that we update to a new backend to continue scaling service. In order to do so we should have a good understanding of what our different options are. Previous research is captured in this sheet: https://docs.google.com/spreadsheets/d/1MXikljoSUVP77w7JKf9EXN40OB-ZkMqT8Y5b2NYVKbU/edit?usp=sharing , but it is outdated. We should re-examine still relevant options as well as new ones along relevant parameters to evaluate good options to replace Blazegraph. AC: 1. a comparison spreadsheet of different graph backend options (similar to previous research) TASK DETAIL https://phabricator.wikimedia.org/T275398 EMAIL PREFERENCES https://phabricator.wikimedia.org/settings/panel/emailpreferences/ To: MPhamWMF Cc: MPhamWMF, Aklapper, CBogen, Akuckartz, Nandana, Namenlos314, Lahi, Gq86, Lucas_Werkmeister_WMDE, GoranSMilovanovic, QZanden, EBjune, merbst, LawExplorer, _jensen, rosalieper, Scott_WUaS, Jonas, Xmlizer, jkroll, Wikidata-bugs, Jdouglas, aude, Tobias1984, Manybubbles, Mbch331
