As a REST service, clients be developed using almost any programming language. The test programs under: h5serv/test/integ illustrate some of the methods for performing different operations using Python.

The related project: https://github.com/HDFGroup/h5pyd provides a (mostly) h5py-compatible interface to the server for Python clients.

For C/C++ clients, the HDF REST VOL is a HDF5 library plugin that enables the HDF5 API to read and write data using HSDS. See: https://bitbucket.hdfgroup.org/users/jhenderson/repos/rest-vol/browse.

HSDS only modifies the S3 bucket that it is configured to use, so to uninstall just remove source files, Docker images, and S3 bucket (or minio directory).
