Yes, that's exactly what's happening.
I'll see maybe just one more compaction, since the biggest sstable is
already more than 20% of residual free space.
For me, the backup strategy shouldn’t drive the rest.
Mhh, yes, that makes sense.
And if your data is ever-growing
and never deleted, you will be adding nodes to handle the extra data as
time goes by (and running clean-up on the existing nodes).
What will happen when adding new nodes, as you say, though?
If I have a 1GB sstable with 250GB of data that will be no longer useful
(as a new node will be the new owner) will that sstable be reduced to
750GB by "cleanup" or will it retain old data?
Thanks,
