Migrate data from MongoDB to Druid

At my workplace, MongoDB is the data source and for analytics we re planning to use Druid but first we have to migrate data from MongoDB. Is there any way to migrate all or required data collections from MongoDB to Druid?

I’m not aware of any tools for doing an automatic MongoDB -> Druid migration, if you’re able to export your data from MongoDB into CSV, JSON, or another format that Druid accepts, you could ingest that exported data.
