[pandasar13]

Pull Request

Description

Add batch_size parameter to init. The batch_size parameter specified in the init of qdrant for the functions get_all_documents(), get_all_documents_generator(), get_documents_by_id(), write_documents() (NOT for update_embeddings) not only ensures that there is consistency with other haystack DocumentStores but also allows to specify the batch_size when initializing the DocumentStore which allows for the use of pipelines in a less constrained manner.
