Is your feature request related to a problem? Please describe.
I could not find a feature to simply convert part of parsed record back to json.
Typical usage for me is when I need to parse deep nested json, extract (lift) and rename some deep fields in it and then return part of parsed record as string.
E.g. using zalando logbook (java spring) can produce json logs, which after parsing look like this:
{
"origin": "remote",
"type": "request",
"correlation": "2d66e4bc-9a0d-11e5-a84c-1f39510f0d6b",
"protocol": "HTTP/1.1",
"sender": "127.0.0.1",
"method": "GET",
"uri": "http://example.org/test",
"host": "example.org",
"path": "/test",
"scheme": "http",
"port": null,
"headers": {
"Accept": ["application/json"],
"Content-Type": ["application/json"]
},
"body": {"test": [1,2,3]}
}
I want to change 'body' value from object to string (e.g. "body": "{\"test\": [1,2,3]}" ).
Describe the solution you'd like
I think it is possible to implement a new 'config_parameter' for filter 'type-converter' to encode record type as json string or may be just another new filter.
Describe alternatives you've considered
I tried to use lua to convert records to json strings, but it implies using an external lua library for that, which is not handy and simple.
