    Method parameters in org.apache.cassandra.db with type arguments of type OnDiskAtom
    Modifier and Type | Method and Description
    --- | ---
    `ColumnIndex` | ColumnIndex.Builder.`buildForCompaction(java.util.Iterator<OnDiskAtom> columns)` The important distinction wrt build() is that we may be building for a row that ends up being compacted away entirely, i.e., the input consists only of expired tombstones (or columns shadowed by expired tombstone).
