dsetool unload_core

Removes a search index for DSE.

The dsetool unload_core command runs on all nodes in the cluster and supports DSE authentication with [-l username -p password].

To drop a search index from a table and delete all related data for the entire cluster, see DROP SEARCH INDEX.

The removal of the secondary index from the table schema is always distributed.

Restriction: Command is supported only on nodes with DSE Search workloads.

Syntax conventions
Syntax conventions	Description
UPPERCASE	Literal keyword.
Lowercase	Not literal.
`Italics`	Variable value. Replace with a valid option or 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.

deleteDataDir=( true | false )

Whether to delete index data and any other artifacts in the solr.data directory.

true - Deletes index data and any other artifacts in the solr.data directory. It does not delete DataStax Enterprise data.
false - Default. Does not delete index data or other artifacts.

deleteResources=( true | false )

Whether to delete the configuration and schema resources associated with the search index. For example, solrconfig.xml and schema.xml.

true - Deletes index resources.
false - Default. Does not delete index resources.

distributed=( true | false )

Whether to have one node or all nodes designated to run the command issue the delete index data command. Setting this option governs only those nodes designated to run the command. But the unload_core command and its deleteResources option control changes in database search index data and schema levels that are visible by all nodes.

true - Default. Run the unload_core command from all nodes designated to run it.
false - Only one node runs the unload_core command.
