I would like to know if it is possible to create a mapping for parent id to
be extracted from the source, instead of specifying in the index request.
I could see that the \_id mapping is possible as below, similarly I looking
for parent id mapping
{
"tweet" : {
"\_id" : {
"path" : "post\_id"
}
}
}

In otherwords
Can I use a "path" for the \_parent field?

By looking into the source code
org.elasticsearch.index.mapper.internal.ParentFieldMapper, it is not
possible.
Can any one confirm?

I don't think it is possible, but since parent is basically an alias for
setting the routing value you can probably use the \_routing field and
related path setting along with the normal parent mapping.

Hello Matt,
Thanks for the reply.
If I set the \_routing filed then the \_parent filed in the source is
optional ?

Actually, now that I think about it this might since it won't set the
\_parent field which I believe is used in the child id cache. I would need
to double check in the source. At any rate, you should open an issue to
support passing in the parent value via a field path during indexing.
