lin001 is 2 vCPU with 3.8 GiB and no swap, shared with 27 other containers.
Cube was rebuilding three pre-aggregations over static fixture data on 10, 10
and 30 minute keys, and its own log shows what that cost:
"Previous interval #19593 was not finished with 30000 interval"
"Interval #19594 finished after 00:02:50"
A refresh taking 2m50s scheduled every 30 seconds, at interval #19594 -
overlapping and never catching up, for days. Every rebuild produced a
byte-identical result, because the fixtures do not change.
24 hours until imh makes the data genuinely live, at which point these get
tuned deliberately rather than left at a number that was never chosen. Cube
also suggests fewer partitions via rollup_lambda; that is a modelling change,
not a demo-day one.
