Is Apache Ignite suited for NoSQL schema

Is JSON within a JSON supported within Apache Ignite? Example:

{ 
    "stuff": {
        "onetype": [
            {"id":1,"name":"John Doe"},
            {"id":2,"name":"Don Joeh"}
        ],
        "othertype": {"id":2,"company":"ACME"}
    }, 
    "otherstuff": {
        "thing": [[1,42],[2,2]]
     }
}

Goal is being able to query based on any field in a JSON. So far with Apache Ignite I have seen that with creating a class and then storing object of it - is possible to add indexes and query json on a first level of Key/Value pairs but did not see any example for a nested JSON.

Is it maybe better to use MongoDB or Cassandra for that kind of need (to index and query any nested field within a JSON)?

JSON is treated as a regular string when it's put into a cache.
When a JSON has only a single level, then it's possible to represent it as either POJO or BinaryObject, put it into a cache and benefit from all the querying capabilities, but nested objects cannot be indexed and queried properly so far.
As an option, you could use ScanQueries
