Joris Van den Bossche commented on ARROW-2051:
----------------------------------------------
What is the exact idea here? To provide a way to construct an array of UUIDs
from python objects? The exact proposed enhancement is not fully clear to me.
But, I would say, as long as we have no UUID type in Arrow (or an extension
type, not sure if there are any plans on that), construction methods for UUID
seems out of scope for pyarrow to me.
> [Python] Support serializing UUID objects to tables
> ---------------------------------------------------
>
> Key: ARROW-2051
> URL: https://issues.apache.org/jira/browse/ARROW-2051
> Project: Apache Arrow
> Issue Type: Bug
> Components: Python
> Affects Versions: 0.8.0
> Reporter: Omer Katz
> Priority: Major
>
> UUID objects can be easily supported and can be represented as 128-bit
> integers or a stream of bytes.
> The fastest way I know to construct a UUID object is by using it's 128-bit
> (16 bytes) integer representation.
>
> {code:java}
> %timeit uuid.UUID(int=24197857161011715162171839636988778104)
> 611 ns ± 6.27 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)
> %timeit uuid.UUID(bytes=b'\x124Vx\x124Vx\x124Vx\x124Vx')
> 1.17 µs ± 7.5 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)
> %timeit uuid.UUID('12345678-1234-5678-1234-567812345678')
> 1.47 µs ± 6.08 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)
> {code}
>
> Right now I have to do this manually which is pretty tedious.
