Hello! Is

zed import

just used for importing some sample data or can we use it to import files with millions of relations? We want to do some performance testing with realistic data.

only used for sample data. For millions of relations, you use the bulk import / export APIs.

this one right? https://buf.build/authzed/api/docs/main:authzed.api.v1#authzed.api.v1.ExperimentalService

correct

great, thank you!
