Considerations
Listed below are some points to consider while working with Virtual Catalogs:
• Virtual Catalog DSL can be executed using
For create/alter/delete - http://localhost:9400/rest/execute/v1/ actions/dsl/invoke
For read - http://localhost:9400/rest/execute/v1/actions/query/invoke
• For annotation QUOTED_STRING, an explicit NULL keyword or a quoted string 'NULL' can be specified. This is to allow annotation to be unset or set to null explicitly.
• Altering a virtual catalog can alter the annotation or rename/relocate the virtual catalog.
