Re: Proposal: File based metastore

Would it be useful to have a tool that can save database(s), table(s) and
partition(s) metadata in a file and then import this file in another
metastore? These files can be stored together with data files or elsewhere.

This would allow for targeted exchange of metadata between multiple HMS
services.

Have you looked at https://cwiki.apache.org/confluence/display/Hive/LanguageManual+ImportExport? Why does this not suit your use case?
