If using the version that has both rt and wt caches, is it just the wt

cache also get polluted?
As I said, all reads go through flashcache, so if you read three 10 GB
sstables for a compaction you will get those 30 GB into the cache.
Of course. I wasn't thinking clearly.
So, back to a previous point you brought up, I will have heavy reads and
even heavier writes. How would you rate the benefits of flashcache in
such a scenario? Is it still an overall performance boost worth the
expense?
