Cassandra DROP IndexDROP INDEX command is used to drop a specified index. If the index name was not specified during index creation, then index name is TableName_ColumnName_idx.
Rules for dropping an Index
- If the index does not exist, it will return an error unless you use IF EXISTS which returns no operation.
- During index creation, you have to specify keyspace name with the index name otherwise index will be dropped from the current keyspace.
Let's take an example to demonstrate how to drop index on a column. Here we drop the created index to a column "student_name" in the table "student". The name of the keyspace is "javatpoint".
Index is dropped from the column "student_name".
You can see that index is not anymore on the table.
