Review Comment:
UCS aims to produce sstables with size between $t / \sqrt 2$ and $t \cdot
\sqrt 2$ (More information can be found
[here](https://github.com/apache/cassandra/blob/cassandra-5.0/src/java/org/apache/cassandra/db/compaction/UnifiedCompactionStrategy.md)).
We should verify that `sizeInBytes < targetSSTableSize * INVERSE_SQRT_2`
