Expand description

Represents a single field in the database.

Fields are grouped by their “Collection Group”, which represent all collections in the database with the same id.

Fields§

§name: String

Required. A field name of the form projects/{project_id}/databases/{database_id}/collectionGroups/{collection_id}/fields/{field_path}

A field path may be a simple field name, e.g. address or a path to fields within map_value , e.g. address.city, or a special field path. The only valid special field is *, which represents any field.

Field paths may be quoted using (backtick). The only character that needs to be escaped within a quoted field path is the backtick character itself, escaped using a backslash. Special characters in field paths that must be quoted include:*, ., ``` (backtick), [, ]`, as well as any ascii symbolic characters.

Examples: (Note: Comments here are written in markdown syntax, so there is an additional layer of backticks to represent a code block) \address.city`represents a field namedaddress.city, not the map key cityin the fieldaddress. ``represents a field named`, not any field.

A special Field contains the default indexing settings for all fields. This field’s resource name is: projects/{project_id}/databases/{database_id}/collectionGroups/__default__/fields/* Indexes defined on this Field will be applied to all fields which do not have their own Field index configuration.

§index_config: Option<IndexConfig>

The index configuration for this field. If unset, field indexing will revert to the configuration defined by the ancestor_field. To explicitly remove all indexes for this field, specify an index config with an empty list of indexes.

§ttl_config: Option<TtlConfig>

The TTL configuration for this Field. Setting or unsetting this will enable or disable the TTL for documents that have this Field.
