DROP INDEX (SAI, SASI, 2i)

Removes an existing index.

For Solr indexes, use DROP SEARCH INDEX.

When you DROP or re-create an SAI index, you cannot use that SAI index (based on the same column) until it has finished building and is queryable. Other queries that don’t use the index aren’t blocked.

Synopsis

DROP INDEX [ IF EXISTS ] [<keyspace_name>.]<index_name> ;

Legend
Syntax conventions	Description
UPPERCASE	Literal keyword.
Lowercase	Not literal.
`< >`	Variable value. Replace with a user-defined value.
`[]`	Optional. Square brackets (`[]`) surround optional command arguments. Do not type the square brackets.
`( )`	Group. Parentheses ( `( )` ) identify a group to choose from. Do not type the parentheses.
`\|`	Or. A vertical bar (`\|`) separates alternative elements. Type any one of the elements. Do not type the vertical bar.
`...`	Repeatable. An ellipsis ( `...` ) indicates that you can repeat the syntax element as often as required.
`'<Literal string>'`	Single quotation (`'`) marks must surround literal strings in CQL statements. Use single quotation marks to preserve upper case.
`{ <key> : <value> }`	Map collection. Braces (`{ }`) enclose map collections or key value pairs. A colon separates the key and the value.
`<<datatype1>,<datatype2>>`	Set, list, map, or tuple. Angle brackets ( `< >` ) enclose data types in a set, list, map, or tuple. Separate the data types with a comma.
`<cql_statement>;`	End CQL statement. A semicolon (`;`) terminates all CQL statements.
`[--]`	Separate the command line options from the command arguments with two hyphens ( `--` ). This syntax is useful when arguments might be mistaken for command line options.
`' <<schema\> ... </schema\>> '`	Search CQL only: Single quotation marks (`'`) surround an entire XML schema declaration.
`@<xml_entity>='<xml_entity_type>'`	Search CQL only: Identify the entity and literal value to overwrite the XML element in the schema and solrConfig files.

IF EXISTS: Optional. Drop the index if it exists, or silently do nothing if the named index doesn’t exist in the keyspace. Otherwise, an error is returned if the index doesn’t exist.
keyspace_name: The name of the keyspace containing the index. If not specified, the current keyspace is used.
index_name: The name of the index to drop.
