How do I use retry_on_conflict to resolve error "ConflictError 409" with update()?

I noticed that if I send too many requests in a short period, my elasticsearch update code throws a 409 ConflictError. Reading a bit into it, I noticed there is a param for update() to set the number of retry attempts, however when I tried using it, I get another error:

RequestError(400, 'action_request_validation_exception', 'Validation Failed: 1: compare and write operations can not be retried;')

How can I handle 409 ConflictError during frequent updates and/or use the retry_on_conflict param?

    thing = Thing.get(id=thing_id, ignore=404)

    if thing:
            return post.update(
                script=update_func,
                refresh=True,
                retry_on_conflict=ES_UPDATE_RETRY_COUNT,
                now=arrow.utcnow().float_timestamp,
            )

ConflictError: ConflictError(409, 'version_conflict_engine_exception', '[TtWP-la58FPHbw]: version conflict, required seqNo [8], primary term [1]. current document has seqNo [9] and primary term [1]')

using elasticsearch-py directly seems to work…

            return post._get_connection().update(
                Post.Index().name,
                post_id,
                body,
                refresh=True,
                retry_on_conflict=10,
            )

This error seems to occur when adding if_seq_no and if_primary_term to the update arguments.

Here’s a temporary solution:

del post.meta['seq_no']
del post.meta['primary_term']
post.update(
    retry_on_conflict=10,
    date=datetime.utcnow(),
)
