Take it as a sanity check more than an exhaustive test, but I just tried saving ~20mb values in a loop in CubDB on my MacBook Pro. I did not incur in specific issues. Performance wise, each write took 0.7 seconds. Reads were much faster. Compaction was also taking more or less 0.7s * N.
I will look into how much of that write performance can be shaved off, but nothing seems to be breaking unexpectedly.
