Best way to convert a record to a Map
What's the best way to get a Map<String, Object> representation of a record?
Thanks,
Mike

Mike,
In JoltTransformRecord I make the following call to do that:
Map<String, Object> recordMap = (Map<String, Object>)
DataTypeUtils.convertRecordFieldtoObject(record,
RecordFieldType.RECORD.getRecordDataType(record.getSchema()));
Regards,
Matt

I would look at ConvertRecord to understand the process and then wrap those values in a map.

Inside the processor.

Probably using a ScriptedWriter with a couple lines of Groovy to form and serialize the Java map. Or are you asking about inside the processor execution?
