Functions

func Collection

func Collection(ctx context.Context, client *mongo.Client, opts Options) error

Collection creates a backup of a collection using the options to describe how to filter or constrain the backup. The option's Target value allows you to produce a writer where the backup will be collected.

Types

type Options

type Options struct {
	NS          model.Namespace `bson:"ns" json:"ns" yaml:"ns"`
	Target      WriterCreator   `bson:"-" json:"-" yaml:"-"`
	Query       interface{}     `bson:"query" json:"query" yaml:"query"`
	Sort        interface{}     `bson:"sort" json:"sort" yaml:"sort"`
	Limit       int64           `bson:"limit" json:"limit" yaml:"limit"`
	IndexesOnly bool            `bson:"indexes_only" json:"indexes_only" yaml:"indexes_only"`
}

Options describes the configuration of the backup, for a single collection. Query, Sort, and Limit are optional, but allow you to constrain the backup.

type WriterCreator

type WriterCreator func(context.Context, string) (io.WriteCloser, error)

WriterCreator provides a way to create writers (e.g. for file or similar,) to support writing backup payloads without requiring this implementation to manage files or file interfaces.
