Description:
Hi all,
a while ago I posted this issue:
[Issue-3866 | {color:#333333}https://issues.apache.org/jira/browse/ARROW-3866{color}]
{color:#333333}While working with Pyarrow I encountered another potential bug related to column metadata: If I create a table containing columns with metadata everything is fine. But after I save the table to parquet and load it back as a table using pq.read_table, the column metadata is gone.{color}
{color:#333333}As of now I can not say yet whether the metadata is not saved correctly or not loaded correctly, as I have no idea how to verify it. Unfortunately I also don't have the time try a lot, but I wanted to let you know anyway.{color}
