Just to see if Tachyon would give me an error about configured memory being more than available I set:
# Some value over combined available mem and disk space.
export TACHYON_WORKER_MEMORY_SIZE=1000GB
And observed the allocation in the web UI without error.
Is some of the info going to be pushed to disk when available RAM is exceeded?
What happens when it exceeds disk space? Dropped file errors or system failure?
