nodetool cleanup

Immediately cleans up keyspaces and tables that no longer belong to a DataStax Enterprise (DSE) node.

OpsCenter provides a Cleanup option in the Nodes UI for Running cleanup.

DSE does not automatically remove data from nodes that lose part of their partition range to a newly added node. After adding a new node, use nodetool cleanup on the source node and on neighboring nodes that shared the same subrange to prevent the database from including the old data to rebalance the load on that node. The nodetool cleanup command temporarily increases the use of disk space proportional to the size of the largest SSTable and may cause an increase in Disk I/O.

Failure to run nodetool cleanup after adding a node may result in data inconsistencies including resurrection of previously deleted data.

Syntax conventions Description

Syntax conventions	Description
Italic, bold, or `< >`	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: `<datatype2` In Search CQL statements, angle brackets are used to identify the entity and literal value to overwrite the XML element in the schema and `solrconfig` files, such as `@<xml_entity>='<xml_entity_type>'`.
`[ ]`	Square brackets surround optional command arguments. Do not type the square brackets.
`( )`	Parentheses identify a group to choose from. Do not type the parentheses.
`\|`	A pipe separates alternative elements. Type any one of the elements. Do not type the pipe.
`...`	Indicates that you can repeat the syntax element as often as required.
`'`	Single quotation marks must surround literal strings in CQL statements. Use single quotation marks to preserve upper case. + For Search CQL only: Single quotation marks surround an entire XML schema declaration, such as `'<<schema> ... </schema>>'`
`{ }`	Map collection. Curly braces enclose maps (`{ <key_datatype>:<value_datatype> }`) or key value pairs (`{ <key>:<value> }`). A colon separates the key and the value.
`;`	Ends a CQL statement.
`--`	Separate command line options from command arguments with two hyphens. This syntax is useful when arguments might be mistaken for command line options.

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: <datatype2

In Search CQL statements, angle brackets are used to identify the entity and literal value to overwrite the XML element in the schema and solrconfig files, such as @<xml_entity>='<xml_entity_type>'.

[ ]

Square brackets surround optional command arguments. Do not type the square brackets.

( )

Parentheses identify a group to choose from. Do not type the parentheses.

|

A pipe separates alternative elements. Type any one of the elements. Do not type the pipe.

...

Indicates that you can repeat the syntax element as often as required.

'

Single quotation marks must surround literal strings in CQL statements. Use single quotation marks to preserve upper case. + For Search CQL only: Single quotation marks surround an entire XML schema declaration, such as '<<schema> ... </schema>>'

{ }

Map collection. Curly braces enclose maps ({ <key_datatype>:<value_datatype> }) or key value pairs ({ <key>:<value> }). A colon separates the key and the value.

;

Ends a CQL statement.

--

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

Options

If an option has a short and long form, both forms are given, separated by a comma.

-h, --host hostname: The hostname or IP address of a remote node or nodes. When omitted, the default is the local machine.
-p, --port jmx_port: The JMX port number.
-pw, --password jmxpassword: The JMX password for authenticating with secure JMX. If a password is not provided, you are prompted to enter one.
-pwf, --password-file jmx_password_filepath: The filepath to the file that stores JMX authentication credentials.
-u, --username jmx_username: The username for authenticating with secure JMX.
-j, --jobs: Specify the number of SSTables affected simultaneously. Set to 0 to use all available compaction threads.

Default: 2
keyspace_name: The keyspace name.

Default: All keyspaces
table_name: The table name.

Examples

Clean up all keyspaces with specified number of jobs

nodetool cleanup -j 1

Clean up single table
