materialized view
C1CEFR level
60/100Rarity: rare
TechnicalRegister
A stored, precomputed query result refreshed on a schedule rather than recalculated on each request.
The daily-active-users figure comes from a materialized view, so the dashboard loads instantly instead of scanning the whole event log.
Rarity runs from 0 (a word everyone knows) to 100 (almost never seen outside specialist or literary writing). Level is the word's real difficulty on the CEFR scale, from A1 to C2.
