Hello,
Could you please share you experience on pushing through a major compaction on
a CF with a large number of sstables? I get an OOM even after dropping CFs that
I can drop and increasing JVM heap to the limit. My caches are minimal and
memtables are empty. This only happens on a single node.

What other options do I have, e.g. reloading this CF or just the segment from
this node? Ideally I would like to avoid custom export/import scripting.
Thank you very much,
Oleg
