)

const DefaultCleanupIntervalSeconds = int64(60)

DefaultCleanupIntervalSeconds can be overwritten on a per-class basis

const DefaultConfigFile string = "./weaviate.conf.json"

DefaultConfigFile is the default file when no config file is provided

const DefaultGossipBindPort = 7946

DefaultGossipBindPort uses the hashicorp/memberlist default port value assigned with the use of DefaultLocalConfig

const DefaultPersistenceDataPath string = "./data"

DefaultPersistenceDataPath is the default location for data directory when no location is provided

const DefaultPersistenceHNSWMaxLogSize = 500 * 1024 * 1024 // 500MB for backward compatibility

const DefaultPersistenceLSMMaxSegmentSize = math.MaxInt64

DefaultPersistenceLSMMaxSegmentSize is effectively unlimited for backward compatibility. TODO: consider changing this in a future release and make some noise about it. This is technically a breaking change.

const DefaultQueryDefaultsLimit int64 = 10

DefaultQueryDefaultsLimit is the default query limit when no limit is provided

const VectorizerModuleNone = "none"

const VectorizerModuleText2VecContextionary = "text2vec-contextionary"

TODO: This should be retrieved dynamically from all installed modules

Variables

var DefaultAuthentication = Authentication{
	AnonymousAccess: AnonymousAccess{
		Enabled: true,
	},
}

DefaultAuthentication is the default authentication scheme when no authentication is provided

var GitHash = "unknown"

GitHash keeps the current git hash commit information

var ServerVersion string

ServerVersion is set when the misc handlers are setup. When misc handlers are setup, the entire swagger spec is already being parsed for the server version. This is a good time for us to set ServerVersion, so that the spec only needs to be parsed once.

Functions

func FromEnv

func FromEnv(config *Config) error

FromEnv takes a *Config as it will respect initial config that has been provided by other means (e.g. a config file) and will only extend those that are set

func GetConfigOptionGroup

func GetConfigOptionGroup() *swag.CommandLineOptionsGroup

GetConfigOptionGroup creates an option group for swagger

Types

type APIKey

type APIKey struct {
	Enabled     bool     `json:"enabled" yaml:"enabled"`
	Users       []string `json:"users" yaml:"users"`
	AllowedKeys []string `json:"allowed_keys" yaml:"allowed_keys"`
}

type AnonymousAccess

type AnonymousAccess struct {
	Enabled bool `json:"enabled" yaml:"enabled"`
}

AnonymousAccess considers users without any auth information as authenticated as "anonymous" rather than denying their request immediately. Note that enabling anonymous access ONLY affects Authentication, not Authorization.

type Authentication

type Authentication struct {
	OIDC            OIDC            `json:"oidc" yaml:"oidc"`

}

Authorization configuration

func (Authorization) Validate

func (a Authorization) Validate() error

Validate the Authorization configuration. This only validates at a general level. Validation specific to the individual auth methods should happen inside their respective packages
