What are the different ways to delete data in HBase?

There are several ways to delete data in HBase.

  1. remove
delete '<table_name>', '<row_key>'
  1. remove all
deleteall '<table_name>', '<row_key>'
  1. remove
delete '<table_name>', '<row_key>', '<column_family>:<column_qualifier>'
  1. Bulk delete: You can use batch operations to delete multiple rows of data.
deleteall '<table_name>', '<row1>', '<row2>', ..., '<rowN>'
  1. To delete all data in a table, you can achieve this by dropping the table and then recreating it.
disable '<table_name>'
drop '<table_name>'
create '<table_name>', '<column_family1>', '<column_family2>', ..., '<column_familyN>'

Please note that the above operations are commands executed in the HBase Shell, and the same operations can also be performed using HBase’s Java API.
