Manual Compaction in cassandra

If Size Tiered Compaction Strategy is used, then on performing manual
compaction would there be always *1 sstable* at last irrespective of the
size?

Also would there be 2 sstables if repair has been performed?

This is version dependent - in newer versions it’ll be one repaired and one I repaired (if you run repairs)

There will be one table after major compaction for all existing tables. But all new sstable will keep on creating while compaction is in progress.
