Shalin Shekhar Mangar commented on SOLR-13320:
----------------------------------------------
Thanks [~dragonsinth] for explaining the use-case and the problem.
These are conflicts -- a document was not the version we wanted it to be. Here
{{-1}} is just a special version that means the document should not have
existed. So I think {{ignoreConflicts}} or {{ignoreVersionConflicts}} is more
appropriate than {{ignoreDuplicates}}. Regardless of what we call the param,
returning a list of docs IDs that were skipped would be nice to have as Gus
noted. {{haltBatchOnError}} is definitely too broad and it is not always
possible to recover from errors e.g. if there is malformed JSON in the middle
of a batch.
> add a param ignoreDuplicates=true to updates to not overwrite existing docs
