Hello Vlad,
I don't remember the context of the sentences, but I see no
incompatibilities. I believe the misunderstanding comes from the word
'compaction' that is a bit large. In the first sentence it is about
tombstone compactions. in sentence two it is about standard, regular
compaction
Hi, thanks for answer!

table defines that tombstones can be purged 1 minute after they were created.If
all rows are created with the same TTL, SSTables

No, it sets a default TTL for the future writes (that is no guarantee, as
it can be overwritten in any specific query).
It seems data to be deleted, but after compaction, I don't see any disk
