Omer Katz created ARROW-2051: -------------------------------- 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
