Tombstones

9 min to complete

What are tombstones and why is it important?
Data written to ScyllaDB gets persisted to SSTables. Since SSTables are immutable, the data can’t actually be removed when a delete is performed, instead, a marker (also called a “tombstone”) is written to indicate the value’s new status. When compaction occurs, the data will be expunged completely and the corresponding disk space recovered.
