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 = }")
print(f"{int(sf) = }")
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)
int(sf) = 856165981072306191
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)
Output:
