Paul Rogers commented on DRILL-4760:
------------------------------------
The penultimate section in the Drill Parquet docs is, "SQL Types to Parquet
Logical Types". The table lists all the Parquet logical (or "original") types.
However, no SQL type is listed for many. When the data is read into Drill,
there must be a type associated with the data. Perhaps the table should list
the Drill data type. And, the data has to be represented as some known JDBC
type in the JDBC driver, so perhaps list that type as well.
> Add technical description of Drill's Parquet support

> Key: DRILL-4760
> URL: https://issues.apache.org/jira/browse/DRILL-4760
> Project: Apache Drill
> Issue Type: Improvement
> Components: Documentation
> Affects Versions: 1.7.0
> Reporter: Paul Rogers
> Priority: Minor
>
> Drill documentation (http://drill.apache.org/docs/parquet-format/) provides a
> description of Drill's Parquet support. However, the material is mostly at
> the "marketing level", describing how wonderful the format is. Those who
> actually build systems would greatly benefit from improved technical content.
> This entry is a place to gather the required information so it is available
> to the Doc. team.
> Some of the proposed material might go into a new "Develper Info" section
> rather than clutter the existing user-oriented Parquet page.
