Mike,
It is currently slated for 1.4. I'm not sure what you mean by "what is the
branch?"
The PR is at [1], and the JIRA is at [2] if that helps. Yes, the Scripted
Lookup Service
would need to return a Record object. If you have a Map<String, String>, for
instance,
you could create a Record Object fairly easily:
final Map<String, String> values = ...;
final List<RecordField> fields = new ArrayList<>();
fields.add(new RecordField("key1", RecordFieldType.STRING.getDataType());
fields.add(new RecordField("key2", RecordFieldType.STRING.getDataType());
fields.add(new RecordField("key3", RecordFieldType.STRING.getDataType());
final RecordSchema schema = new SimpleRecordSchema(fields);
return new MapRecord(values, schema);
Thanks

LookupService have to build a real Record object or would a Map be sufficient?
Thanks,

Mike,
I also have a Pull Request in that allows a Record to be returned from a
LookupService and then have LookupRecord
add all of the fields of that Record to the incoming data instead of adding the
Record itself. So, for example,
you could have a Scripted LookupService return a record like:
{
"key1": "value1",
"key2": "value2",
"key3": "value3"
}
And then LookupRecord would insert all of those values into your incoming
Record as desired. So I would expect that
update should be in the next release.
Thanks
