robert3005 opened a new issue, #1252:
URL: https://github.com/apache/arrow-java/issues/1252

   ### Describe the enhancement requested
   
   Right now the library integrating with arrow-java needs to resort to hacks 
of setting environment variable or system property at runtime if it knows its 
usages of arrow-java can omit null and bounds checking. However, that is not 
true for all of the usages in the given process leading to invalid data reads 
or segfaults. 
   
   To avoid this pitfall I suggest we add getUnchecked apis that NEVER do any 
null and bound checking but put the responsibility on the caller to guard 
against their possibility. For example in apache iceberg 
https://github.com/apache/iceberg/blob/23b5ce8eeca2d894c7973e19caa5c5ec02b4e4b8/spark/v4.1/spark/src/main/java/org/apache/iceberg/spark/data/vectorized/VectorizedSparkParquetReaders.java#L44-L51
 
   
   These apis would make it easy to mix libraries that use arrow as an 
implementation detail along with user code that operates directly on arrow 
arrays
