I have a time series of string-formatted UUIDs, and I would like Polars to translate them into u128 numbers for better storage and querying.
Similar to what we do with dates:
....str.to_datetime("%Y-%m-%dT%H:%M:%S.%fZ", strict=False)
Is this supported, or do I need to handle it on the Python side?
Also, I don't see a u128
type, but there's a Decimal
that seems to be an i128
. If I were to do my own translation, which type should I use?
P.S. I notice a GitHub ticket in the Polars repository about supporting the Rust crate Uuid
, but in a way, this could be implemented without it. So, I am not sure if it is.
Polars doesn't support a u128
dtype. If you can accept the loss, you can store them as u64
or otherwise as a Utf8
column.
We haven't support for this yet, but we will also get FixedSizeBinary
in the future which could also fit this.
