Copy of the index with specified sample size

Elastic Stack Elasticsearch

Is there a way to make a copy of the index into another cluster with just a sample of the source index? I'm using ES6 and wanted to see if there are any easier ways to get a sample of the index for testing purposes?

Thanks!

Hey,

how about using reindex from remote with a query to limit the data? See https://www.elastic.co/guide/en/elasticsearch/reference/6.3/docs-reindex.html#reindex-from-remote

Thanks for the pointer, will give it a try. Not sure how it works but will it be a random sample if I do a limit?

no, it is not random. Either a document matches or does not match the query, sorting does not matter. Hope that makes sense.
