	Viper   *viper.Viper
	Key     string
	Context context.Context
	Options *Options

	SubViper *viper.Viper
	// contains filtered or unexported fields
}

func New 

func New(app *wst.IApp, dsKey string, dsViper *viper.Viper, parentContext context.Context) *Datasource

func (*Datasource) Close added in v1.6.13 

func (ds *Datasource) Close() error

func (*Datasource) Count added in v1.5.40 

func (ds *Datasource) Count(collectionName string, lookups *wst.A) (int64, error)

func (*Datasource) Create 

func (ds *Datasource) Create(collectionName string, data *wst.M) (*wst.M, error)

func (*Datasource) DeleteById

func (*Datasource) DeleteMany added in v1.6.13 

func (ds *Datasource) DeleteMany(collectionName string, whereLookups *wst.A) (result DeleteResult, err error)

whereLookups is in the form of [ 

{
  "$match": {
    "name": "John"
  }
}

] and is used to filter the documents to delete. It cannot be nil or empty.

func (*Datasource) FindMany 

func (ds *Datasource) FindMany(collectionName string, lookups *wst.A) (MongoCursorI, error)

FindMany retrieves data from the specified collection based on the provided lookup conditions using the appropriate data source connector specified in the configuration file. @param collectionName string: the name of the collection from which to retrieve data. @param lookups *wst.A: a pointer to an array of conditions to be used as lookup criteria. If nil, all data in the collection will be returned. @return MongoCursorI: a cursor to the result set that matches the lookup criteria, or an error if an error occurs while attempting to retrieve the data. The cursor needs to be closed outside of the function. Implementations for Redis and memorykv connectors are not yet implemented and will result in an error.
