Hi,
you can truncate datetimes like this (in pyspark), e.g. to 5 minutes:
import pyspark.sql.functions as F
df.select((F.floor(F.col('myDateColumn').cast('long') / 300) *
300).cast('timestamp'))
Best,

Hello,
maybe broadcast can help you here. [1]
You can load the model once on the driver and then broadcast it to the
workers with `bc_model = sc.broadcast(model)`? You can access the model in
the map function with `bc_model.value()`.

Hi,
depending on what you're trying to achieve `RDD.toLocalIterator()` might
help you.

You're right, it's not security groups but you can configure a VPC endpoint

Hello,
`itertools.groupby` is evaluated lazily and the `g`s in your code are
generators not lists. This might cause your problem. Casting everything to
lists might help here, e.g.:
grp2 = [(k, list(g)) for k,g in groupby(grp1, lambda e: e[1])]

Hello Abhishek,
your code appears ok. Can you please post the exception you get? Without,
it's hard to track down the issue.
