dsetool index_checks (experimental)

Optional and experimental. Reads the full index and optionally performs sanity checks. No repairs or fixes occur. Run only when index is inactive. No writes are allowed while index check is running.

Running this index check is time consuming and implies a hard commit.

Restriction: Command is supported only on nodes with DSE Search workloads.

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.

keyspace_name.table_name

Required. The keyspace and table names of the search index. Keyspace and table names are case-sensitive. Enclose names that contain uppercase in double quotation marks.

coreOptions=<yamlFilepath>

When auto-generation is on with generateResources=true, the file path to a customized YAML-formatted file of options. See Changing auto-generated search index settings.

coreOptionsInline=key1:value1#key2:value2#…

Use this key-value pair syntax key1:value1#key2:value2# to specify values for these settings:

auto_soft_commit_max_time:ms
default_query_field:field
distributed:(true|false)
enable_string_copy_fields:(true|false)
exclude_columns: col1, col2, col3, …
generate_DocValues_for_fields:( * | field1, field2, … )
generateResources:(true|false)

See Changing auto-generated search index settings.

--index_checks=true|false

Specify to run the index check.

true - Runs the index check to verify index integrity. Reads the full index and has performance impact.
false - Default. Does not run the index check.

--index_checks_stop=true|false

Specify to stop the index check.

true - Requests the index check to stop.
false - Does not stop the index check.

Examples

Ensure that indexing is inactive before doing an index check.

To do an index check:

dsetool index_checks demo.health_data
