Explain deletion in hbase? Mention what are the three types of tombstone markers in hbase?
Answer / Shailly Saxena
Deletion in Apache HBase doesn't delete data immediately but marks it as deleted with Tombstone markers. There are three types of tombstone markers: Major, Minor, and Visible. Major tombstones are created when a row is completely deleted. Minor tombstones occur during compactions, and Visible tombstones are used to mark the deletion of a specific cell within a row.
