Wan Kun created SPARK-46403:
-------------------------------
Summary: Decode parquet binary dictionary with getBytesUnsafe
method
Key: SPARK-46403
URL: https://issues.apache.org/jira/browse/SPARK-46403
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 4.0.0
Reporter: Wan Kun
Now spark will get a parquet binary dictionary object with getBytes() method.
The *Binary.getBytes()* method will always make a new copy of the internal
bytes.
We can use *Binary.getBytesUnsafe()* method to get the cached bytes if it has
already been called getBytes() and has the cached bytes.
