A metro feature, keyed by NavBoost feature id V2. This can be a metro id, a boost, or extended in the future to add probabilities or weights.

Salient Countries is an estimated probability (salience) of a doc to be relevant to a country. On this message, countries are represented as int32 (the format of this data is defined in i18n/identifiers/stableinternalregionconverter.cc). Salience is a value in range [0.0 – 1.0] in which 1.0 represents a high likelihood to be relevant to the country

Proto contains parameters of a single component distribution.

Protocol record used for collecting together all information about a document. Please consult go/dj-explorer for two basic questions about CompositeDoc: – Where should I look up certain information (e.g: pagerank, language)? – What does each field in CompositeDoc mean and who should I contact if I have questions? To add a new field into CompositeDoc, or change existing field’s size significantly, please file a ticket at go/dj-new-field, fill in necessary information and get approved by docjoin-access@ team. Next id: 194

Alternate names are some urls that we would like to associate with documents in addition to canonicals. Sometimes we may want to serve these alternatenames instead of canonicals. Alternames in CompositeDoc should come from WebMirror pipeline.

The top forwarding dups of the canonical url. (note: it may actually include some dups that are NOT used for forwarding data but for making "info:" complete)

Contains information mostly used within indexing (e.g. not used for building the production serving shards). Most of this data is generated only in Alexandria, however there are exceptions.

Contains information for a live experiment.

Contains information about the partial updates present in a partial CompositeDoc.
