Sure, np. We did same W/A for long period, but eventually it indeed impacted very much our application performance, and partial atomic updates to parent doc improved this significantly (20-30x than whole docs).

Although I have to admit that this is not the response that I was hoping for 😊. Upgrading to Solr 8 is currently not possible for us because we found multiple issues when doing so (see http://mail-archives.apache.org/mod_mbox/lucene-solr-user/202005.mbox/%3Ce7dc73d4be2ac35404db0f6cfb75f905%40mail.gmail.com%3E). We have now implemented a workaround and send the whole document with ChildDocs to Solr instead of doing an atomic update. This works as expected but is significantly slower.

See the below item and it's last comments with details: https://issues.apache.org/jira/browse/SOLR-12638?focusedCommentId=16894628&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-16894628 Eventually we have move to Solr 8.3 and it's working there as expected with the above mentioned changes.

Suppose I have committed the following documents to the index: [ { "id": "1", "testString": "1", "testInt": "1", "_childDocuments_": [ { "id": "1.1", "child_type": "child_a", "testString": "1.1", "testInt": "1" }, { "id": "1.2", "child_type": "child_a", "testString": "1.1", "testInt": "1" } ] } ] <uniqueKey> is id, all fields are indexed. Now I want to update testInt to 2 on the parent document without losing the parent child relation (ChildDocTransformerFactory should still produce correct results). I tried the following variants, both not successful: *Variant 1:* Sending the following update document to the update-Endpoint [ { "id": "1", "testInt": { "set": "2" } } ] The parent document is updated, but the ChildDocTransformerFactory does not return any child documents *Variant 2:* Sending the following update document to the update-Endpoint [ { "id": "1", "testInt": { "set": "2" }, "_childDocuments_": [ { "id": { "set": "1.1" } }, { "id": { "set": "1.2" } } ] } ] Same result: Parent is updated, but ChildDocTransformerFactory does not return any child documents Is there any other way of doing a partial update without losing the parent child relation? Resending the complete document with all attributes and children would work but is inefficient for us (we had to load all documents from Solr before resending them).
