I am new to mongodb and my task is to export metadata about all collections in a database. I know little about shell scripting and i am not able to understand the documents provided on mongodb website.
I am using Mongodb compass 4.2.14 and though i am able to export the collection, i am not able to just export the column names.
How do i export just the column names and also how to view the metadata?
In Compass GUI, select the Schema TAB, and click the Analyze button. This will show the data types for each field for a collection.
To get a copy of the schema, from the top-left menu, select the Collection -> Share Schema as JSON menu item. This will copy the schema to the Clipboard. You can then paste from the clipboard into any text file/editor of your choice.
