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:

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


sudo pip install scidb4py


sudo python install


Iterating through array item-by-item

from scidb4py import Connection
conn = Connection('localhost', 1239)
array = conn.execute("select * from array(<a:int32>[x=0:3,2,0], '[0,1,2,3]')")
for pos, val in array:
    print '%d - %d' % (pos['x'], val['a'])

Iterating through array chunk-by-chunk, item-by-item

from scidb4py import Connection
conn = Connection('localhost', 1239)
array = conn.execute("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]]')")
while not array.end:
    while not array.chunk_end:
        print '%s - %s' % (array.get_coordinates(), array.get_item("a"))



  • Fixed bug #15 (Large chunk can not fit single network message)
  • Fixed reading strings greater than 8 bytes from RLE chunks
  • Added ‘active’ property to Connection which indicate active query
  • Basic query autocomplete and autocancel. Complete by default.


  • Fixed bug #14 (Strange bzipped chunk issue)
  • Fixed bug #5 (Compressed chunk support)
  • scidb4py now provide __version__ string
