Grote (95Mb) JSON-array opsplitsen in kleinere brokken?

In Python:

import json
with open('file.json') as infile:
  o = json.load(infile)
  chunkSize = 1000
  for i in xrange(0, len(o), chunkSize):
    with open('file_' + str(i//chunkSize) + '.json', 'w') as outfile:
      json.dump(o[i:i+chunkSize], outfile)
