dsetool unload_core

Removes a search index.

Removes a search index. 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 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 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.
Valid values:
  • 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 resources associated with the search index. For example, solrconfig.xml and schema.xml.
Valid values:
  • true - Deletes index resources.
  • false - Default. Does not delete index resources.
distributed=( true | false )
Whether to distribute and apply the operation to all nodes in the local datacenter.
  • True applies the operation to all nodes in the local datacenter.
  • False applies the operation only to the node it was sent to. False works only when recovery=true.

Default: true

Warning: Distributing a re-index to an entire datacenter degrades performance severely in that datacenter.
