The logical identifiers allow PubSub objects be found in the PubSub configuration.

PubSub Connection Name, Writer Group Name, and DataSet Writer Name

A PubSub configuration contains a collection of PubSub connections, and each PubSub connection is identified by its name, which is a string. For publishers, a PubSub connection determines the physical publisher Id that is used by that publisher.

A PubSub connection contains a collection of writer groups, and each writer group is also identified by its name (a string). Each writer group has its physical writer group Id specified.

A writer group contains a collection of dataset writers, and each dataset writer is also identified by its name (a string). Each dataset writer has its physical dataset wroiter Id specified.

Published Dataset Name

In a PubSub configuration, each published dataset has a unique name (a string). Published datasets may be organized in a tree of (named) dataset folders. The name of published dataset, however, must still be unique across the whole PubSub configuration, not just in its dataset folder.

A dataset writer may be associated with a published dataset by means of published dataset name.
