Pure python SciDB client library implementation
Project description
Pure python SciDB client library.
This library aims to provide access to SciDB server through native network protocol based on protobuf. It still on early stages of development, so do not expect complete features support and stable work :)
Any feedback and patches are welcome: https://github.com/artyom-smirnov/scidbpy/
Runtime dependencies
python >= 2.7 or pypy >= 1.8 (python 3 not supported yet)
python-protobuf >= 2.4
bitstring
Build dependencies
protobuf-compiler >= 2.4
Installation
sudo pip install scidbpy
or
sudo python setup.py install
Examples
Iterating through array item-by-item
from scidbpy import Connection conn = Connection('localhost', 1239) conn.open() conn.prepare("select * from array(<a:int32>[x=0:3,2,0], '[0,1,2,3]')") array = conn.execute() for pos, val in array: print '%d - %d' % (pos['x'], val['a']) conn.close()
Iterating through array chunk-by-chunk, item-by-item
from scidbpy import Connection conn = Connection('localhost', 1239) conn.open() conn.prepare("select * from array(<a:int32 null>[x=0:2,3,0, y=0:2,3,0], '[[1,2,3][4,5,6][7,8,9]]')") array = conn.execute() while not array.end: while not array.chunk_end: print '%s - %s' % (array.get_coordinates(), array.get_item("a")) array.next_item() array.next_chunk() conn.close()
