Hi,
I want to propose a discussion about upgrading the minimum JDK
version of the Gravitino server to 17 while keeping the Gravitino
client and Spark&Flink connector JDK version to 8 to keep
compatibility.
Recently, I'm working on upgrading the Iceberg version from 1.6 to
1.9 for IRC to support more interfaces. Still, Iceberg 1.7 drops the
support for JDK8, so I had to split Iceberg code to common-module
which contains legacy code for old version and modern-module which
contains the code for Iceberg new version. User could choose the
Iceberg version when compiling Gravitino, and we should provide
Gravitino server and IRC server for old and new Iceberg version
seperately. Please refer to
https://github.com/apache/gravitino/pull/7418 for more details. It's
hard to maintain for both the developer and the user.
So how about upgrading our Gravitino server min JDK version to 17
and leave Gravitino clients and connectors to 8, just like Trino
server using High JDK version while Trino client using low JDK
version? This will make the trade-off better for compatibility and
simple usage, and maintenance of Gravitino.
Best,
Xiaojing
