--------------------------------
Summary: 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
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.
