Hi,

What's the most efficient way to dump data from Elasticsearch? Is something like this the best option?

Thanks

If you have access to kibana, you can use the built in report generator tool.

you can create backup files with simple queries, by also specifying the location of the backup

elasticdump is what I use and its very fast and effective. If you think its slow try to change the parameters
