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.

keyspace_name table_name

Keyspace table pair.

keys_per_range

The approximate number of rows per subrange.

start_token

The start token of a specified range of tokens.

end_token

The end token of a specified range of tokens.

Example

To run the command:

dsetool list_subranges demo health_data 10000 113427455640312821154458202477256070485 0

The subranges are output and can be used as input to the nodetool repair command.
