Cassandra Compaction and Tombstone Behavior: Leveled vs. SizeTiered Compaction

Compactions in Cassandra can be contentious due to their impact on I/O load as well as increased disk space availability requirements. A primer in compaction will be provided, and the differences in Cassandra's data organization and tombstone handling between Leveled and SizeTiered compaction strategies will be discussed. What is compaction? Compaction is a maintenance process which re-organizes SSTables to optimize data structures on disk as well as reclaim unused space.
