EnsureFulltextIndexOptions

EnsureFulltextIndexOptions: { fields: [string]; minLength?: undefined | number; name?: undefined | string; type: "fulltext" }

Options for creating a fulltext index.

Type declaration

  • fields: [string]

    An array containing exactly one attribute path.

  • Optional minLength?: undefined | number

    Minimum character length of words to index.

  • Optional name?: undefined | string

    A unique name for this index.

  • type: "fulltext"

    Type of this index.

EnsureGeoIndexOptions

EnsureGeoIndexOptions: { fields: [string, string]; geoJson?: undefined | false; name?: undefined | string; type: "geo" } | { fields: [string]; geoJson?: undefined | false | true; name?: undefined | string; type: "geo" }

Options for creating a geo index.

EnsureHashIndexOptions

EnsureHashIndexOptions: { deduplicate?: undefined | false | true; fields: string[]; name?: undefined | string; sparse?: undefined | false | true; type: "hash"; unique?: undefined | false | true }

(MMFiles only.) Options for creating a hash index.

When using the RocksDB storage engine, this index type behaves identically to EnsurePersistentIndexOptions.

Type declaration

  • Optional deduplicate?: undefined | false | true

    If set to false, array values will not be deduplicated.

    Default: true

  • fields: string[]

    An array of attribute paths.

  • Optional name?: undefined | string

    A unique name for this index.

  • Optional sparse?: undefined | false | true

    If set to true, the index will omit documents that do not contain at least one of the attribute paths in fields and these documents will be ignored for uniqueness checks.

    Default: false

  • type: "hash"

    Type of this index.

  • Optional unique?: undefined | false | true

    If set to true, a unique index will be created.

    Default: false

EnsurePersistentIndexOptions

EnsurePersistentIndexOptions: { fields: string[]; name?: undefined | string; sparse?: undefined | false | true; type: "persistent"; unique?: undefined | false | true }

Options for creating a persistent index.

Type declaration

  • fields: string[]

    An array of attribute paths.

  • Optional name?: undefined | string

    A unique name for this index.

  • Optional sparse?: undefined | false | true

    If set to true, the index will omit documents that do not contain at least one of the attribute paths in fields and these documents will be ignored for uniqueness checks.

    Default: false

  • type: "persistent"

    Type of this index.

  • Optional unique?: undefined | false | true

    If set to true, a unique index will be created.

    Default: false

EnsureSkiplistIndexOptions

EnsureSkiplistIndexOptions: { deduplicate?: undefined | false | true; fields: string[]; name?: undefined | string; sparse?: undefined | false | true; type: "skiplist"; unique?: undefined | false | true }

(MMFiles only.) Options for creating a skiplist index.

When using the RocksDB storage engine, this index type behaves identically to EnsurePersistentIndexOptions.

Type declaration

  • Optional deduplicate?: undefined | false | true

    If set to false, array values will not be deduplicated.

    Default: true

  • fields: string[]

    An array of attribute paths.

  • Optional name?: undefined | string

    A unique name for this index.

  • Optional sparse?: undefined | false | true

    If set to true, the index will omit documents that do not contain at least one of the attribute paths in fields and these documents will be ignored for uniqueness checks.

    Default: false

  • type: "skiplist"

    Type of this index.

  • Optional unique?: undefined | false | true

    If set to true, a unique index will be created.

    Default: false

EnsureTtlIndexOptions

EnsureTtlIndexOptions: { expireAfter: number; fields: [string]; name?: undefined | string; type: "ttl" }

Options for creating a TTL index.

Type declaration

  • expireAfter: number

    Duration in seconds after the attribute value at which the document will be considered as expired.

  • fields: [string]

    An array containing exactly one attribute path.

  • Optional name?: undefined | string

    A unique name for this index.

  • type: "ttl"

    Type of this index.

FulltextIndex

FulltextIndex: GenericIndex & { fields: [string]; minLength: number; type: "fulltext" }

An object representing a fulltext index.

GenericIndex

GenericIndex: { id: string; name?: undefined | string; sparse: boolean; unique: boolean }

Shared attributes of all index types.

Type declaration

  • id: string

    A unique identifier for this index.

  • Optional name?: undefined | string

    A unique name for this index.

  • sparse: boolean

    Whether documents not containing at least one of the attribute paths are omitted by this index.

  • unique: boolean

    Whether this index enforces uniqueness for values of its attribute paths.

GeoIndex

GeoIndex: GenericIndex & { bestIndexedLevel: number; fields: [string] | [string, string]; geoJson: boolean; maxNumCoverCells: number; type: "geo"; worstIndexedLevel: number }

An object representing a geo index.

HashIndex

HashIndex: GenericIndex & { fields: string[]; selectivityEstimate: number; type: "hash" }
