Hi community,

We used composite runtime fields in the Elasticsearch java client. But since we moved to the new Elasticsearch client, composite runtime fields are not longer supported.  
Are these runtime fields deprecated? Are they supposed to come back or have they been replaced with something new?

Would it be possible to re-add them to the new client?
