                 Key: PARQUET-11
                 URL: https://issues.apache.org/jira/browse/PARQUET-11
             Project: Parquet
          Issue Type: Bug

I encountered OOMs reading metadata for a dataset with 500+ columns, many of 
them quite sparse.

We can reduce memory utilization significantly.
