The key of the root block is returned to the client.29Retrieval: given the key of the root block, the DPA retrieves the block chunks and reconstructs the original data and passes it back as a lazy reader. A lazy reader is a reader with on-demand delayed processing, i.e. the chunks needed to reconstruct a large file are only fetched and processed if that particular part of the document is actually read.30As the chunker produces chunks, DPA dispatches them to its own chunk store31implementation for storage or retrieval.32*/33const (34	storeChanCapacity           = 10035	retrieveChanCapacity        = 10036	singletonSwarmDbCapacity    = 5000037	singletonSwarmCacheCapacity = 50038	maxStoreProcesses           = 839	maxRetrieveProcesses        = 840)41var (42	notFound = errors.New("not found")43)44type DPA struct {45	ChunkStore46	storeC    chan *Chunk47	retrieveC chan *Chunk48	Chunker   Chunker49	lock    sync.Mutex50	running bool51	quitC   chan bool52}53// for testing locally54func NewLocalDPA(datadir string) (*DPA, error) {55	hash := MakeHashFunc("SHA256")56	dbStore, err := NewDbStore(datadir, hash, singletonSwarmDbCapacity, 0)57	if err != nil {58		return nil, err59	}60	return NewDPA(&LocalStore{61		NewMemStore(dbStore, singletonSwarmCacheCapacity),62		dbStore,63	}, NewChunkerParams()), nil64}65func NewDPA(store ChunkStore, params *ChunkerParams) *DPA {66	chunker := NewTreeChunker(params)67	return &DPA{68		Chunker:    chunker,69		ChunkStore: store,70	}71}72// Public API.
