dsetool list_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 diagrams and code samples use one or more of these styles to mark placeholders for variable values. Replace placeholders with a valid option or your own user-defined value. In CQL statements, angle brackets are required to enclose data types in a set, list, map, or tuple.
Separate the data types with a comma.
For example: In Search CQL statements, angle brackets are used to identify the entity and literal value to overwrite the XML element in the schema and |

Separate command line options from command arguments with two hyphens. This syntax is useful when arguments might be mistaken for command line options. |

Example
To run the command:
dsetool list_subranges demo health_data 10000 113427455640312821154458202477256070485 0
