A logical repository (storage system) of {@link Dataset}s.
Implementations of {@code DatasetRepository} are storage systems that containzero or more {@link Dataset}s. A repository acts as a factory, as well as a registry, of datasets. Users can {@link #create(String,DatasetDescriptor)} anew {@link Dataset} with a name and schema, or retrieve a handle to anexisting dataset, by name, by way of the {@link #load(String)} method. Whilenot expressly forbidden, most repositories are expected to support only a single concrete {@link Dataset} implementation.
No guarantees are made as to the durability, reliability, or availability of the underlying storage. That is, a {@code DatasetRepository} could be ondisk, in memory, or some combination. See the implementation class for details about the guarantees it provides.
Implementations of {@link DatasetRepository} are immutable.
