CF conventions multi-dimensional array storage on top of Booklet

cfdb is a pure Python database for managing labeled multi-dimensional arrays following the CF conventions. It is an alternative to netCDF4/xarray, built on Booklet for local file storage and EBooklet for S3 sync. Thread-safe and multiprocessing-safe via locks.

Installation

pip install cfdb

Quick Example

import cfdb
import numpy as np

with cfdb.open_dataset('example.cfdb', flag='n') as ds:
    lat = ds.create.coord.lat(data=np.linspace(-90, 90, 181, dtype='float32'))
    lon = ds.create.coord.lon(data=np.linspace(-180, 180, 361, dtype='float32'))
    temp = ds.create.data_var.generic('temperature', ('latitude', 'longitude'), dtype='float32')
    temp[:] = np.random.rand(181, 361).astype('float32') * 40 - 10

with cfdb.open_dataset('example.cfdb') as ds:
    for slices, data in ds['temperature'].iter_chunks(include_data=True):
        print(slices, data.shape)
