Nick DiQuattro commented on ARROW-9676:
---------------------------------------
Nope! The map will sometimes run to completion, sometimes inconsistent rows
will fail. Maybe I'll have to try again after that nested struct issue you
linked above is resolved. Thanks again!
> [R] Error converting Table with nested structs
> ----------------------------------------------
>
> Key: ARROW-9676
> URL: https://issues.apache.org/jira/browse/ARROW-9676
> Project: Apache Arrow
> Issue Type: New Feature
> Components: R
> Affects Versions: 1.0.0
> Environment: Amazon Linux, 32gb of ram
> Reporter: Nick DiQuattro
> Priority: Major
>
> When trying to collect data from a dataset based on parquet files with nested
> structs (column is a struct with 2 structs nested) of moderate size (1Mish
> rows), R crashes. If I add a filter to reduce the number of rows, the data is
> parsed. If I select out the struct column, it works great (up to 21M rows).
> My hunch is the structs resulting in data.frame columns may be the issue. I
> am curious if there's a way to have arrow import structs as lists instead of
> data.frames. Thanks for the direction to here [~neilr8133]!
