> Key: DRILL-3963
> URL: https://issues.apache.org/jira/browse/DRILL-3963
> Project: Apache Drill
> Issue Type: New Feature
> Reporter: amit hadke
> Assignee: amit hadke
>
> Sequence files store list of key-value pairs. Keys/values are of type hadoop
> writable.
> Provide a format plugin that reads raw bytes out of sequence files which can
> be further deserialized by a udf(from hadoop writable -> drill type)
