[jira] [Updated] (SPARK-53047) Mordernize Spark to use the latest Java features
[ https://issues.apache.org/jira/browse/SPARK-53047?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Dongjoon Hyun updated SPARK-53047:
----------------------------------
Description:
This issue aims to modernize Spark by taking advantage of all Java features which are available since Java 17. In general, these Java's built-in implementations are much faster than Scala 2.13.x or 3rd party libraries and guarantees a complete benefit of the future Java 25.
|| VERSION || JEP ||
| Java 9 | JEP 280: Indify String Concatenation (https://openjdk.org/jeps/280) |
| Java 9 | `InputStream.transferTo` |
| Java 9 | `InputStream.readAllBytes` |
| Java 11 | `String.isBlank` |
| Java 11 | `String.repeat` |
| Java 11 | `Files.readString` |
| Java 11 | `Files.writeString` |
| Java 14 | JEP 359: Records (Preview) (https://openjdk.org/jeps/359) |
| Java 15 | JEP 384: Records (Second Preview) (https://openjdk.org/jeps/384) |
| Java 16 | JEP 395: Records (https://openjdk.org/jeps/395) |
