Hello,
Le 20/10/2022 à 17:32, John Muehlhausen a écrit :
if (fieldNullCount < 0)
{
throw new InvalidDataException("Null count length must
be >= 0"); // TODO:Localize exception message
}
Above from Ipc/ArrowReaderImplementation.cs.
pyarrow is fine with -1, probably due to the following. It would be
nice if C# were brought up to speed.
Do you know of any IPC writers that emit -1 here?
It is not explicitly allowed by the spec:
