Is the document to be validated loaded completely in memory

[rmuller]

It is not clear to me if the document to be validated loaded completely in memory or it is processed in a streaming mode.
If it is completely loaded in memory, is there a way to enable a streaming mode? If not, any suggestions how to implement this?

Yes it's completely loaded into memory with a call to Jackson's ObjectMapper.readTree. The api is such that it calls validate with the JsonNode of the current instance data and the JsonNode of the root instance data.

It's not possible to enable a streaming mode. I don't really have an idea of how you can implement this generically.

If what you have is a document with an array of objects, you could stream and process each object individually with a json schema for each object.

Indeed the JSON file exists of a header object and an array with a huge amount of array elements.
The solution you propose is the same i was thinking of (we do the same in the XML world). Wanted to be sure this is also in this case the best approach. Thanks for your quick reply!
