Ben Kietzman created ARROW-7081: ----------------------------------- Summary: [R] Add methods for introspecting parquet files Key: ARROW-7081 URL: https://issues.apache.org/jira/browse/ARROW-7081 Project: Apache Arrow Issue Type: Improvement Components: R Affects Versions: 0.15.1 Reporter: Ben Kietzman Assignee: Neal Richardson Fix For: 1.0.0
Parquet files are very opaque, and it'd be handy to have an easy way to introspect them. Functions exist for loading them as a table, but information about row group level metadata and data page compression is hidden. Ideally, every structure from https://github.com/apache/parquet-format/#file-format could be examined in this fashion. -- This message was sent by Atlassian Jira (v8.3.4#803005)
