Types

type IndexDocumentFromDB

type IndexDocumentFromDB struct {
	Options bson.M `bson:",inline"`
	Key     bson.D `bson:"key"`
}

IndexDocumentFromDB is used internally to preserve key ordering.

type InputOptions

type InputOptions struct {
	Query          string `long:"query" short:"q" description:"query filter, as a v2 Extended JSON string, e.g., '{\"x\":{\"$gt\":1}}'"`
	QueryFile      string `long:"queryFile" description:"path to a file containing a query filter (v2 Extended JSON)"`
	ReadPreference string `` /* 220-byte string literal not displayed */
	TableScan      bool   `long:"forceTableScan" description:"force a table scan"`
}

InputOptions defines the set of options to use in retrieving data from the server.

func (*InputOptions) GetQuery

func (inputOptions *InputOptions) GetQuery() ([]byte, error)

func (*InputOptions) HasQuery

func (inputOptions *InputOptions) HasQuery() bool

func (*InputOptions) Name

func (*InputOptions) Name() string

Name returns a human-readable group name for input options.

type Metadata

type Metadata struct {
	Options bson.M   `json:"options,omitempty"`
	Indexes []bson.D `json:"indexes"`
	UUID    string   `json:"uuid,omitempty"`
}

Metadata holds information about a collection's options and indexes.

type MongoDump

type MongoDump struct {
	// basic mongo tool options
	ToolOptions   *options.ToolOptions
	InputOptions  *InputOptions
	OutputOptions *OutputOptions

	// Skip dumping users and roles, regardless of namespace, when true.
	SkipUsersAndRoles bool

	ProgressManager progress.Manager

	// useful internals that we don't directly expose as options
	SessionProvider *db.SessionProvider

	// Writer to take care of BSON output when not writing to the local filesystem.
	// This is initialized to os.Stdout if unset.
	OutputWriter io.Writer
	// contains filtered or unexported fields
}

MongoDump is a container for the user-specified options and internal state used for running mongodump.
