--------------------------------

             Summary: Introduce a `putByteArrays` method to `WritableColumnVector` to support setting multiple duplicate `byte[]`
                 Key: SPARK-39202
                 URL: https://issues.apache.org/jira/browse/SPARK-39202
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 3.4.0
            Reporter: Yang Jie


Add a  `putByteArrays` method to `WritableColumnVector`

 
{code:java}
int putByteArrays(int rowId, int total, byte[] value) {code}
 

 

this method used to support setting multiple duplicate `byte[]` to `WritableColumnVector`.

Since `byte[] value` is fixed length, memory can allocated at one time without calling `

reserve(int requiredCapacity)` method many times.

 

This method is applicable to `ColumnVectorUtils.populate` method with `StringType` and partial `DecimalType` scenario, this corresponds to the Vectorized Partition Column filling of Parquet and Orc
