In UnsafeRow, we use the private field of BigInteger for better performance, but it actually didn't contribute much (3% in one benchmark) to end-to-end runtime, and make it not portable (may fail on other JVM implementations). So we should use the public API instead. cc rxin Author: Davies Liu <[email protected]> Closes #8286 from davies/portable_decimal. (cherry picked from commit 270ee67) Signed-off-by: Davies Liu <[email protected]>
