parallel_bulk not actually doing anything

I’m trying to make reindexing big indices faster.

    for response in helpers.parallel_bulk(target_client, _change_doc_index(docs, target_index),
                                          chunk_size=10, thread_count=10, ** kwargs):
        print("response", response)

Nothing appears to happen… Switching to regular bulk things work fine…

Also, siginterrupt doesn’t work with parallel bulk running

Hey, thanks. This solved my problem.

for r in parallel_bulk(es, qs):
    pass

I don’t really need the return results. So I was wondering why bulk(es, qs) work and parallel_bulk(es, qs) does not at first.

parallel_bulk is a generator so you need to iterate over it to get to the results, see https://github.com/elastic/elasticsearch-py/issues/336
