Hello, We currently have two ES clusters which do not normally communicate with one another (though they could). I would like to import the indexes from cluster A into cluster B, without destroying the indexes that are already present in cluster B. Furthermore, I do not want the indexes from cluster B to exist in cluster A (i.e. uni-directional relationship). What would be the safest way to do this? How about the fastest? Bonus points if it's the same answer for both questions. 🙂 Thank you! -- Daniel Maher What no spouse of a writer can ever understand is that a writer is working when he's staring out the window. ---

Would a scan and bulk index be fast enough for you? I think that would be the safest.

Thank you for your response; I was actually hoping for some sort of hackery that would allow me to simply import the filesystem tree or something, but the scan / bulk index approach seems to be the winner. -- Daniel Maher There's small choice in rotten apples. -- William Shakespeare, "The Taming of the Shrew" ---

Scan / bulk indexing is the way to go. At least for now.
