langchain_community.document_loaders.concurrent.ConcurrentLoader¶

class langchain_community.document_loaders.concurrent.ConcurrentLoader(blob_loader: BlobLoader, blob_parser: BaseBlobParser, num_workers: int = 4)[source]¶

Load and pars Documents concurrently.

A generic document loader.

Parameters

  • blob_loader (BlobLoader) – A blob loader which knows how to yield blobs

  • blob_parser (BaseBlobParser) – A blob parser which knows how to parse blobs into documents

  • num_workers (int) –

Methods

__init__(blob_loader, blob_parser[, num_workers])

A generic document loader.

alazy_load()

A lazy loader for Documents.

aload()

Load data into Document objects.

from_filesystem(path, *[, glob, exclude, ...])

Create a concurrent generic document loader using a filesystem blob loader.

get_parser(**kwargs)

Override this method to associate a default parser with the class.

lazy_load()

Load documents lazily with concurrent parsing.

load()

Load data into Document objects.

load_and_split([text_splitter])

Load all documents and split them into sentences.
__init__(blob_loader: BlobLoader, blob_parser: BaseBlobParser, num_workers: int = 4) → None[source]¶

A generic document loader.

Parameters

  • blob_loader (BlobLoader) – A blob loader which knows how to yield blobs

  • blob_parser (BaseBlobParser) – A blob parser which knows how to parse blobs into documents

  • num_workers (int) –

Return type

None

async alazy_load() → AsyncIterator[Document]¶

A lazy loader for Documents.

Return type

AsyncIterator[Document]

async aload() → List[Document]¶

Load data into Document objects.

Return type

List[Document]

classmethod from_filesystem(path: Union[str, Path], *, glob: str = '**/[!.]*', exclude: Sequence[str] = (), suffixes: Optional[Sequence[str]] = None, show_progress: bool = False, parser: Union[Literal['default'], BaseBlobParser] = 'default', num_workers: int = 4, parser_kwargs: Optional[dict] = None) → ConcurrentLoader[source]¶

Create a concurrent generic document loader using a filesystem blob loader.

Parameters

  • path (Union[str, Path]) – The path to the directory to load documents from.

  • glob (str) – The glob pattern to use to find documents.

  • suffixes (Optional[Sequence[str]]) – The suffixes to use to filter documents. If None, all files matching the glob will be loaded.

  • exclude (Sequence[str]) – A list of patterns to exclude from the loader.

  • show_progress (bool) – Whether to show a progress bar or not (requires tqdm). Proxies to the file system loader.

  • parser (Union[Literal['default'], ~langchain_core.document_loaders.base.BaseBlobParser]) – A blob parser which knows how to parse blobs into documents

  • num_workers (int) – Max number of concurrent workers to use.

  • parser_kwargs (Optional[dict]) – Keyword arguments to pass to the parser.

Return type

ConcurrentLoader

static get_parser(**kwargs: Any) → BaseBlobParser¶

Override this method to associate a default parser with the class.

Parameters

kwargs (Any) –

Return type

BaseBlobParser

lazy_load() → Iterator[Document][source]¶

Load documents lazily with concurrent parsing.

Return type

Iterator[Document]

load() → List[Document]¶

Load data into Document objects.

Return type

List[Document]

load_and_split(text_splitter: Optional[TextSplitter] = None) → List[Document]¶

Load all documents and split them into sentences.

Parameters

text_splitter (Optional[TextSplitter]) –

Return type

List[Document]
