[jira] [Created] (PARQUET-2204) TypedColumnReaderImpl::Skip should reuse scratch space

fatemah created PARQUET-2204:
--------------------------------

             Summary: TypedColumnReaderImpl::Skip should reuse scratch space
                 Key: PARQUET-2204
                 URL: https://issues.apache.org/jira/browse/PARQUET-2204
             Project: Parquet
          Issue Type: Improvement
            Reporter: fatemah


TypedColumnReaderImpl::Skip allocates scratch space on every call. The scratch space is used to read rep/def levels and values and throw them away. The memory allocation slows down the skip based on microbenchmarks. The scratch space can be allocated once and re-used.
