Hi, I'm wondering why python blow up a dictionary structure so much.
The ids and cat substructure could have 0..n entries but in the most cases they are <= 10,t is limited by <= 6. Thanks for any advice to save memory. Christian Example: {'0a0f7a3a0e09826caef1bff707785662': {'ids': {'aa316b86-8169-11e6-bab9-0050563e2d7c', 'aa3174f0-8169-11e6-bab9-0050563e2d7c', 'aa319408-8169-11e6-bab9-0050563e2d7c', 'aa3195e8-8169-11e6-bab9-0050563e2d7c', 'aa319732-8169-11e6-bab9-0050563e2d7c', 'aa319868-8169-11e6-bab9-0050563e2d7c', 'aa31999e-8169-11e6-bab9-0050563e2d7c', 'aa319b06-8169-11e6-bab9-0050563e2d7c'}, 't': {'type1', 'type2'}, 'dt': datetime.datetime(2016, 9, 11, 15, 15, 54, 343000), 'nids': 8, 'ntypes': 2, 'cat': [('ABC', 'aa316b86-8169-11e6-bab9-0050563e2d7c', '74', ''), ('ABC','aa3174f0-8169-11e6-bab9-0050563e2d7c', '3', 'type1'), ('ABC','aa319408-8169-11e6-bab9-0050563e2d7c','3', 'type1'), ('ABC','aa3195e8-8169-11e6-bab9-0050563e2d7c', '3', 'type2'), ('ABC','aa319732-8169-11e6-bab9-0050563e2d7c', '3', 'type1'), ('ABC','aa319868-8169-11e6-bab9-0050563e2d7c', '3', 'type1'), ('ABC','aa31999e-8169-11e6-bab9-0050563e2d7c', '3', 'type1'), ('ABC','aa319b06-8169-11e6-bab9-0050563e2d7c', '3', 'type2')]}, I did a fresh read from pickled object to have a "clean" env. linux-64bit: sys.getsizeof(superdict) 50331744 len(superdict) 941272 VmPeak: 2981364 kB VmSize: 2850288 kB VmLck: 0 kB VmPin: 0 kB VmHWM: 2108936 kB VmRSS: 1978076 kB VmData: 2541724 kB VmStk: 140 kB VmExe: 4 kB VmLib: 111136 kB VmPTE: 4380 kB VmSwap: 0 kB -- https://mail.python.org/mailman/listinfo/python-list
