Is Magma currently ready for 10s or 100s of GB of data?
Or maybe soon?
Outside of moving from the all or nothing of the image, a what point
(size) does the image start losing advantages as a data store?
In that vein, is there a point where an image is larger than desired
from a caching point of view?
I know there may not be any hard data, or even honest opinions regarding
such. But if you have any opinions or data for some possible best
practices regarding such, it would be greatly appreciated.
