Changes in 0.13.0.dev0

Enhancements

• xcube Server has been rewritten almost from scratch.

  • Introduced a new endpoint ${server_url}/s3 that emulates
    and AWS S3 object storage for the published datasets. (#717)
    The bucket name can be either:

    • s3://datasets - publishes all datasets in Zarr format.
    • s3://pyramids - publishes all datasets in a multi-level levels
      format (multi-resolution N-D images)
      that comprises level datasets in Zarr format.

    Datasets published through the S3 API are slightly
    renamed for clarity. For bucket s3://pyramids:

    • if a dataset identifier has suffix .levels, the identifier remains;
    • if a dataset identifier has suffix .zarr, it will be replaced by
      .levels only if such a dataset doesn't exist;
    • otherwise, the suffix .levels is appended to the identifier.
      For bucket s3://datasets the opposite is true:
    • if a dataset identifier has suffix .zarr, the identifier remains;
    • if a dataset identifier has suffix .levels, it will be replaced by
      .zarr only if such a dataset doesn't exist;
    • otherwise, the suffix .zarr is appended to the identifier.

    With the new S3 endpoints in place, xcube Server instances can be used
    as xcube data stores as follows:

    store = new_data_store(
        "s3", 
        root="datasets",   # bucket "datasets", use also "pyramids"
        max_depth=2,       # optional, but we may have nested datasets
        storage_options=dict(
            anon=True,
            client_kwargs=dict(
                endpoint_url='http://localhost:8080/s3' 
            )
        )
    )

  • The limited s3bucket endpoints are no longer available and are
    replaced by s3 endpoints.

  • The --show option of xcube serve is no longer available. (#750)
    We may reintroduce it, but then with a packaged build of
    xcube Viewer that matches the current xcube Server version.

• xcube Server's colormap management has been improved in several ways:

  • Colormaps are no longer managed globally. E.g., on server configuration
    change, new custom colormaps are reloaded from files.
  • Colormaps are loaded dynamically from underlying
    matplotlib and cmocean registries, and custom SNAP color palette files.
    That means, latest matplotlib colormaps are now always available. (#687)
  • Colormaps can now be reversed (name suffix "_r"),
    can have alpha blending (name suffix "_alpha"),
    or both (name suffix "_r_alpha").
  • Loading of custom colormaps from SNAP *.cpd has been rewritten.
    Now also the isLogScaled property of the colormap is recognized. (#661)
  • The module xcube.util.cmaps has been redesigned and now offers
    three new classes for colormap management:
    • Colormap - a colormap
    • ColormapCategory - represents a colormap category
    • ColormapRegistry - manages colormaps and their categories

Other

• Deprecated CLI xcube tile has been removed.

• Deprecated modules, classes, methods, and functions
  have finally been removed:

  • xcube.core.geom.get_geometry_mask()
  • xcube.core.mldataset.FileStorageMultiLevelDataset
  • xcube.core.mldataset.open_ml_dataset()
  • xcube.core.mldataset.open_ml_dataset_from_local_fs()
  • xcube.core.mldataset.open_ml_dataset_from_object_storage()
  • xcube.core.subsampling.get_dataset_subsampling_slices()
  • xcube.core.tiledimage
  • xcube.core.tilegrid

• The following classes, methods, and functions have been deprecated:

  • xcube.core.xarray.DatasetAccessor.levels()
  • xcube.util.cmaps.get_cmap()
  • xcube.util.cmaps.get_cmaps()

• Fixed problem with xcube gen raising FileNotFoundError
  with Zarr >= 2.13.
