             Summary: Improve parquet reading performance for String/Binary type based on Buffer operations instead of BinaryArrayBuilder
                 Key: ARROW-17735
                 URL: https://issues.apache.org/jira/browse/ARROW-17735
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Parquet
    Affects Versions: 8.0.1
            Reporter: xiangxiang Shen


Improve parquet reading performance for String/Binary type based on Buffer operations instead of BinaryArrayBuilder.

 

Currently, parquet String/Binary type reading is not good enough. For fixedwidth types， the Reader has adopted Buffer operations  instead of ArrayBuilder interfaces.

 

So it‘s better to use Buffer operations in String/Binary type reading.
