The decision was defined together by the Search Team at Wikimedia
Foundation and the people in charge of Wikidata at Wikimedia
Deutschland. In particular, Lydia Pintscher is ultimately responsible
for all Wikidata product decisions at WMDE.
I would like to stress how this decision was not taken lightheartedly.
It's been three years that we know that Blazegraph is on the verge of
failing, we wrote a playbook in case of dramatic failure,[1] and we
evaluated several alternatives to Blazegraph,[2] each with its pros
and cons.
While evaluating which way to go, knowing that no solution would be a
"magic wand" that would magically solve all our problems - in fact, no
"magic solution" exists, each comes with its load of problems and
costs - we came to terms with the fact that we needed more time and
the split was a harsh, but ultimately effective solution to buy some
time in the transition to the next backend.
Hope this helps.
