dask.array.to_tiledb

dask.array.to_tiledb(darray, uri, compute=True, return_stored=False, storage_options=None, key=None, **kwargs)[source]

Save array to the TileDB storage format

Save ‘array’ using the TileDB storage manager, to any TileDB-supported URI, including local disk, S3, or HDFS.

See https://docs.tiledb.io for more information about TileDB.

Parameters
darray: dask.array

A dask array to write.

uri:

Any supported TileDB storage location.

storage_options: dict

Dict containing any configuration options for the TileDB backend. see https://docs.tiledb.io/en/stable/tutorials/config.html

compute, return_stored: see ``store()``
key: str or None

Encryption key

Returns
None

Unless return_stored is set to True (False by default)

Notes

TileDB only supports regularly-chunked arrays. TileDB tile extents correspond to form 2 of the dask chunk specification, and the conversion is done automatically for supported arrays.

Examples

>>> import dask.array as da, tempfile
>>> uri = tempfile.NamedTemporaryFile().name
>>> data = da.random.random(5,5)
>>> da.to_tiledb(data, uri)
>>> import tiledb
>>> tdb_ar = tiledb.open(uri)
>>> all(tdb_ar == data)
True
