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.


The short form and long form parameters are comma-separated.

Command arguments

-b, --block-size size_in_bytes

Preferred block size in bytes for files in new directory.

Default is 64 MB.

-c, --compression-encoder encoder_name

The compression encoder name. DSE ships with the LZ4 compression encoder.


New directory on DSEFS file system.

  • Explicit file system prefixes dsefs: and file: are supported.


Synchronize files in this directory with the storage device when closed. Files created in the directory inherit the option.

-m, --permission-mode permission_mode

Octal representation of permission mode for owner, group, and others:

  • 0 — no permission

  • 1 — execute

  • 2 — write

  • 3 — write and execute

  • 4 — read

  • 5 — read and execute

  • 6 — read and write

  • 7 — read, write, and execute


Do not synchronize files in this directory with the storage device when closed. Files created in the directory inherit the option.

-n, --redundancy-factor num_nodes

Set the number of replicas of file data, similar to the replication factor in the database keyspaces, but more granular.

  • Set this to one number greater than the number of nodes that are allowed to fail before data loss occurs. For example, set this value to 3 to allow 2 nodes to fail.

  • For simple replication, use a value that is equivalent to the replication factor.

  • Default value is inherited from the parent directory if set, otherwise it is 3.

-p, --parents

If needed, makes parent directories. If parent directories exist, no error.


Make new directory with 32-MB block sizes, redundancy factor or 2, files synchronize on close

dsefs dsefs:// > mkdir -b 32000000 -n 2 --force-sync file:new_directory
