> S3-compatible object storage

Does this mean mimikv can use S3 to store data? Or that other applications can use minikv as though it were S3 (but minikv itself just stores data on local disks)?

minikv implements an S3-compatible API, so you can use S3 clients/tools to PUT and GET objects through its HTTP endpoints—just like a real S3 server.

However, all storage is managed locally (in-memory, RocksDB, or Sled) by minikv. It does not use AWS S3 or any cloud storage as a backend; minikv itself stores your data on local disks.

So: applications can use minikv as if it were S3, but minikv stores data locally (not in S3).
