Hi Jim, Thanks for the response and advice.
My use case is purely export / dump (including ephemeral nodes) and load - I looked at kazoo, but it didn't seem to provide that functionality, where zc.zk did. Do you know where the dump/load functionality would fit in future plans? Or if there's a better option for dump and load? I tried a few options (zktreeutil crashed due to long strings, guano had issues with long file names etc). > Maybe. Not sure nodes with spaces in the names is a good idea. You're right that as a client, putting spaces in node names is not a great idea because many tools don't handle them. But I figure if the client has already written nodes with spaces to Zookeeper, the dump tool should dump them that way instead of failing. Kind of like the robustness principle of "Be conservative in what you send, be liberal in what you accept", the client shouldn't be creating nodes with space names, but the tool will be more robust if it can handle that. As far as I can tell from the docs, spaces are not illegal in ZK path names. Either way, that may be irrelevant if I should be looking elsewhere for dump and load functionality - interested to hear your take. Thanks again for the detailed reply, Dave.
