Property Description sn\_cdm.variable\_regex The regex used to capture variables referenced in a CDI value. With this value, the syntax to use a variable is: ``` @@name@@ ``` Default: @@\(\[^@\].\*?\)@@ sn\_cdm.cdm\_queue\_request\_expiry\_time\_ms The maximum time for a process to be available for processing before it is marked as expired. Default: 900000 ms \(15 min\) sn\_cdm.cdm\_validation\_timeout\_ms The maximum time limit for a validation of a snapshot. Default: 900000 ms \(15 min\) sn\_cdm.default\_node\_identifier\_keys The keys used to identify node objects within an array node. Default: \(none\) sn\_cdm.execute\_exporter\_async\_for\_standard\_request If set to `false`, exporter requests skip the request queue and their output is returned immediately. Changing this setting may decrease system performance if there are many export requests. Default: true sn\_cdm.exception\_enabled If set to false, the control exception functionality is disabled regardless of other policy settings. Default: true sn\_cdm.node\_name\_allowed\_character\_regex The regex used to validate the name of a node. Default allowed characters are: ``` 0-9, A-Z, a-z, _, -, ., %, $, whitespace, :, # ``` Default: `[\\w-.% :$#]` sn\_cdm.app\_name\_allowed\_character\_regex The regex used to validate the name of an application. Default allowed characters are: ``` 0-9, A-Z, a-z, _,-, ., whitespace, |, :, [], (), %, $, # ``` Default: `[\\w-.%$#() :|[\\]]` sn\_cdm.snapshot\_name\_allowed\_character\_regex The regex used to validate the name of a snapshot. Default allowed characters are: ``` 0-9, A-Z, a-z, _,-, ., % ``` Default: `[\\w-.%]` sn\_cdm.exporter\_name\_allowed\_character\_regex The regex used to validate the name of an exporter. Default allowed characters are: ``` 0-9, A-Z, a-z, _,-, .,% ``` Default: `[\\w-.%]` sn\_cdm.exporter\_argument\_name\_allowed\_character\_regex The regex used to validate the name of an exporter argument. Default allowed characters are: ``` 0-9, A-Z, a-z, _ ``` Default: `[\\w]` sn\_cdm.cdm\_max\_allowed\_open\_changesets The maximum allowed number of open changesets. Default: 10 sn\_cdm.preventative\_duplicate\_node\_name\_check If set to true, validating for node name duplication will check name usage across all other open changesets as well \(as opposed to limiting the check within the changeset\). Default: false sn\_cdm.max\_allowed\_upload\_file\_size The maximum payload size for upload of config data via the REST API. Default: 5 MB sn\_cdm.max\_allowed\_cdi\_per\_application The maximum number of CDIs allowed per application. If the number is exceeded, further upload of config data via the REST APIs is blocked. Increasing this limit may significantly decrease performance and break UI functionality. If you change the value, you must recalculate the CDI usage data by running the following command: ``` new sn_cdm.CdmApplicationManager().updateCdiCountOfApplications(); ``` Default: 100000 sn\_cdm.max\_allowed\_cdi\_per\_deployable The maximum number of CDIs allowed per deployable. If the number is exceeded, further upload of config data via the REST APIs is blocked. Increasing this limit may significantly decrease performance and break UI functionality. If you change the value, you must recalculate the CDI usage data by running the following command: ``` new sn_cdm.CdmApplicationManager().updateCdiCountOfApplications(); ``` Default: 10000 sn\_cdm.max\_nodes\_in\_memory The maximum number of nodes that can be supported when using the `queryTree` method of `CdmQuery`. Default: 10000 sn\_cdm.reserved\_node\_names Names that cannot be used for nodes. Default: vars, collections, deployables, components sn\_cdm.max\_allowed\_cdi\_per\_shared\_component The maximum number of CDIs allowed per shared component. If the number is exceeded, further upload of config data via the REST APIs is blocked. Increasing this limit may significantly decrease performance and break UI functionality. If you change the value, you must recalculate the CDI usage data by running the following command: ``` new sn_cdm.CdmApplicationManager().updateCdiCountOfApplications(); ``` Default: 10000 sn\_cdm.max\_allowed\_cdi\_per\_library The maximum number of CDIs allowed per shared component library. If the number is exceeded, further upload of config data via the REST APIs is blocked. Increasing this limit may significantly decrease performance and break UI functionality. If you change the value, you must recalculate the CDI usage data by running the following command: ``` new sn_cdm.CdmApplicationManager().updateCdiCountOfApplications(); ``` Default: 10000 sn\_cdm.attachment.display\_mime\_types File types for which the content preview is available on the Preview pane. You can add additional MIME types to display in the Preview pane. However, the preview is not available for binary file MIME types, such as audio, image, and video. Default: `text/yaml,text/css,text/csv,text/html,text/javascript,text/plain,text/richtext,text/x-vcard,text/x-vcalendar,application/xml,application/javascript,application/json`
