write_parquet failure when Posixct column class has some "NA"

[alvarocombo]

Hi,

When tried to write a data.frame that has Posixct columns where some values are NA, write_parquet throws the following error:

> write_parquet(df, "my.parquet")
Error in write_parquet(df, "my.parquet") : 
  Cannot write unknown column type

The minimal example:

df <- data.frame(
  a = c(1,2),
  t = c(Sys.time(), NA)
)

write_parquet(df, "my.parquet")

The only solution seems to convert them to numeric... which causes a cascade of problems.

Thank you for your attention.

This works fine for me with the dev version of nanoparquet.

Thanks for your prompt response.

I'm using latest stable (0.3.1), on Windows. Any schedule for next stable version (that hopefully solve this issue)?

I can confirm both the failure with 0.3.1 and the subsequent success with 0.3.1.9000.
