dsetool reload_core

Reloads the search index to recognize changes to schema or configuration. Supports DSE authentication with [-l <username> -p <password>].

To reload the core and prevent reindexing, accept the default values reindex=false and deleteAll=false.


dsetool reload_core <keyspace_name>.<table_name>
[coreOptions=<yamlFile> | coreOptionsInline=<key1:value1#key2:value2#...>]
Syntax conventions Description


Literal keyword.


Not literal.


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.


Set, list, map, or tuple. Angle brackets ( < > ) enclose data types in a set, list, map, or tuple. Separate the data types with a comma.


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.


Search CQL only: Identify the entity and literal value to overwrite the XML element in the schema and solrconfig files.


Path of the UTF-8 encoded search index schema file. Cannot be specified when generateResources=true.

To ensure that non-indexed fields in the table are retrievable by queries, you must include those fields in the schema file. For more information, see Solr single-pass CQL queries.


Path of the UTF-8 encoded search index configuration file. Cannot be specified when generateResources=true.


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.

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


Whether to reindex the data when search indexes are auto-generated with generateResources=true. Reindexing works on a datacenter (DC) level. Reindex only once per search-enabled DC. Repeat the reindex command on other data centers as required.

Valid values:

  • true - Default. Reindexes the data. Accepts reads and keeps the current search index while the new index is building.

  • false - Does not reindex the data. You can check and customize search index resources before indexing.

deleteAll=( true|false )
  • true - deletes the already existing index before reindexing; search results will return either no or partial data while the index is rebuilding.

  • false - does not delete the existing index, causing the reindex to happen in-place; search results will return partially incorrect results while the index is updating. Default.

During reindexing, a series of criteria routes sub-queries to the nodes most capable of handling them. See Shard routing for distributed queries.


To make the pending search index active:

dsetool reload_core demo.health_data coreOptionsInline="directory_factory_class:solr.EncryptedFSDirectoryFactory"

To upload the changed resource file:

dsetool reload_core demo.health_data coreOptionsInline="directory_factory_class:solr.EncryptedFSDirectoryFactory"
