Hello dumps users and re-users!
As you know, some wikis are large enough that we produce dumps of some files in 6 pieces in parallel. We'll begin doing this for svwiki starting on July 1. You can follow along on https://phabricator.wikimedia.org/T226200 if interested. If you have not previously worked with a wiki large enough to have files split up, you can look at e.g. frwiki or itwiki dumps to see what files are produced.
Thanks to Ebonetti90 for the request!
Ariel
