DROP Index in Cassandra

Cassandra DROP Index
To drop a specified index in Cassandra, the DROP INDEX command is used. The index name is TableName_ColumnName_idx, in case if the index name was not specified during index creation.

Syntax 2:

Drop index IF EXISTS Keyspace_Name.Index_Name

Important Points:

  • An error will be displayed by default if the index does not exist.
  • The keyspace name needs to be specified with the index name during the index creation or else the index will be dropped from the current keyspace.


Drop index IF EXISTS example.name

Here, the ‘example’ is the keyspace that contains the table ’employees’. The ‘name’ is a column in the ’employees’ table. We are dropping the index from the ‘name’ column.
