They are seeing Arrays and Structs based on the schema of the JSON document.
{
"event_params":[ {"key":"Value"}, {"Key","value"}],
"geolocation": { "lat": 56.333333, "lng": 57.44333 }
}
If this is my JSON document, when I run the crawler it will result in this schema
event_params: Array
geolocation: Struct
The customer can use Custom Classifiers in Glue to extract the data further. Or, they can keep it as is, and run a glue job to format the data into a new table in columnar format.
