gen = SnowflakeGenerator(42)

for i in range(100):
    val = next(gen)
    print(val)

Output:

Parse snowflake id

from snowflake import Snowflake

sf = Snowflake.parse(856165981072306191, 1288834974657)

print(f"{sf.timestamp = }")
print(f"{sf.instance = }")
print(f"{sf.epoch = }")
print(f"{sf.seq = }")
print(f"{sf.seconds = }")
print(f"{sf.milliseconds = }")
print(f"{sf.datetime = }")

Output:

sf.timestamp = 204125876682
sf.instance = 363
sf.epoch = 1288834974657
sf.seq = 15
sf.seconds = 1492960851.339
sf.milliseconds = 1492960851339
sf.datetime = datetime.datetime(2017, 4, 23, 15, 20, 51, 339000)

Load generator state

from snowflake import SnowflakeGenerator, Snowflake

sf = Snowflake.parse(856165981072306191, 1288834974657)
gen = SnowflakeGenerator.from_snowflake(sf)

for i in range(100):
    val = next(gen)
    print(val)
