Advanced Configuration
Web Studio
The
Implementation/SharedObjects/Interfaces/Discovery/folder in the Project tree is a folder that holds all Catalog and Discovery process-related configuration files:
- The MTable subfolder holds the MTables used by the Catalog's various processes. In addition, when Build Artifacts is performed, the Catalog artifact file called catalog_field_info.csv is also created in this folder.
- The plugins.discovery is a configuration file that defines a list of plugins and their execution order. Starting Fabric V8.0, the file exists in this location only when project-level overrides have been performed. Click here for more details about this file.
Show Catalog Commands is a Web Studio setting that either shows or hides the Catalog's related commands Run Discovery Job and Open in Catalog in the Web Studio.
- By default, Show Catalog Commands is enabled.
- This setting can be updated using the Web Studio's user preferences.
Catalog Application Configuration
The properties-info.JSON is a configuration file used by the Catalog Application to determine the view and behavior of various Catalog application elements. This JSON file defines for example:
- Which properties are editable (via manual override) in the Properties tab;
- Which properties are searchable via the Advanced Search screen.
The file is located in fabric/staticWeb/catalog folder and can be updated on the project level.
General
NEO4J_SERVER_MEMORY_HEAP_MAX_SIZE_MB parameter in the [data_discovery] section of config.ini specifies the maximum heap size for the Neo4j server. By default, it is set to 2048 Mb.
- The Neo4j heap size is set when starting Neo4j in a space.
- This value can be adjusted, based on the data platform size and the number of schemas. For example, when an expected data platform size is large, it is recommended to increase this setting.
- To update the heap size in an existing space, stop Neo4j and the DATA_DISCOVERY_JOB, update this setting in config.ini and run the Discovery Job.
ENABLE_DATA_DISCOVERY is a hidden configuration parameter that defines whether the Discovery should be enabled in the system (if neo4j is part of the Fabric space). By default it is set to true. If the Fabric space doesn’t include neo4j, ENABLE_DATA_DISCOVERY should be added to this section and set to false.
