You can set a collection in read only mode after indexing your content into it using MODIFYCOLLECTION. That will effectively give you a read-only collection which does not allow any updates.

My recommendation for your other case would be to have that field present on each document instead of as a separate document (which sure, that'd work as well). But if your number of documents is very large, add a separate document with the metadata you need.

However, you can also use MODIFYCOLLECTION for this to attach properties to the collection itself:

The attributes that can be modified are:

• other custom properties that use a property. prefix

So you can add property.client_version and property.populated_datetime properties to the collection itself, which would then be replicated properly across your cluster if needed. The collection also have a last index update time available, but this might be node specific (since the commits can happen in different timeframes on each node). It won't let you attach the client version anyhow.

The JsonPath engine is known to have issues with such complex expressions. Please use karate.filter() instead which I am sure you will agree is much more readable: https://github.com/intuit/karate#json-transforms

Would this be something you were looking for?
