I am trying to determine which would be a better fit for a large bulk upload ( ~ 1 trillion items for a single index). I have tried with the http api, but its very slow and painful (it has taken a week and only inserted 112 billion items sofar). I imagine I would see a performance boost from using one of the native connectors. Which connector, Transport or Node, would give me the great performance and parallelism?

Appreciate the help.

This might be better in the ES category rather than the hadoop one, as it seems more general?

You can move threads, just edit the topic and change the category 🙂
