dsetool list_subranges

Lists the subranges of data in a keyspace to describe a token range by a number of smaller subranges.

Lists the subranges of data in a keyspace by dividing a token range into a number of smaller subranges. Useful when the specified range is contained in the target node's primary range.

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.
Start Token                             End Token                               Estimated Size
