Thank you @nealrichardson. Over in the related issue at data.table, @rikivillalba confirmed your comment re inability to save the .internal.selfref pointer, they also made the following observation: > The key is in the help of Arrow's [read_parquet](https://arrow.apache.org/docs/r/reference/read_parquet.html#value) > It returns a tibble, not a data.table object. > For some reason, that read function also sets the "class" attribute of the object to their original value of "data.table". So R recognizes it as a data.table even when not really created as is. Assuming they're correct about the read function setting the class attribute, that seems like something that should be changed? either leaving the class as tibble, thus matching the docs, or updating the docs and adding an exception in the read function to not set the class to data.table, because it isn't. -- This is an automated message from the Apache Git Service.
