By enabling REEF to read parquet file, we could potentially integrate with those frameworks. Currently we want to only support data of non-nested types with a table-like property. This allows us to transform the data into formats like RDDs, etc. > A draft of ParquetReader is provided here in a PR: https://github.com/apache/reef/pull/1283 -- This message was sent by Atlassian JIRA (v6.3.15#6346)
