Syntax conventions Description

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.

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.

Definition

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_name

New directory on DSEFS file system.

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

--force-sync

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

--no-force-sync

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.

Examples

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

dsefs dsefs://127.0.0.1:5598/ > mkdir -b 32000000 -n 2 --force-sync file:new_directory
