Are bulk index operations serialized?

[_markus]

@_markus

because to me, the time window I need to fetch the current version to send it with the _bulk request seems race-condition prone to me too

You can use optimistic concurrency control for this.

Can you give a small example how this could work in practice? I'm not sure I properly understand this enough to go about an implementation.

Using an external poses additional complexity so I would prefer one without.

thanks
