cloud-array 0.0.7

Cloud implementation of array for Big Data

Cloud Array

cloud-array is an open-source Python library for storing and streaming large Numpy Arrays on local file systems and major cloud providers CDNs. It automatically chunks a large array of data into arbitrary chunks sizes and uploads them into the targeted direcotry.

import numpy as np
from cloud_array import CloudArray

shape = (10000, 100, 100)
chunk_shape = (10, 10, 10)

f = np.memmap(
   'memmapped.dat',
   dtype=np.float32,
   mode='w+',
   shape=shape
)

array = CloudArray(
   chunk_shape=chunk_shape,
   array=f,
   url="s3://example_bucket/dataset0"
)
array.save()
print(array[:100,:100,:100])
