wangxiyuan commented on FLINK-13598:
------------------------------------
Yes, I tried and built Frocksdb 5.17.2 successful on ARM64[1]. And it's used
for daily arm64 test[2]. It looks that all work well in Flink[3].
Although Rocksdb supports arm64 in its new release, Frocksdb is a fork from
Rocksdb and has its own private change and the higher Rocksdb version has some
perforamance issue. So that we can't upgrade Frocksdb to a newer Rocksdb
version.
For Frocksdb 5.17.2 itself, the problem is that the test (run `make
check_some`) can't be fully passed on arm64. Base on the test I ran a few
months ago, there are 1-3 test failures. (I can't remember the exact number).

> Project: Flink
> Issue Type: Sub-task
> Components: Runtime / State Backends
> Affects Versions: 1.9.0, 2.0.0
> Reporter: wangxiyuan
> Priority: Major
>
> Flink now uses frocksdb which forks from rocksdb for module
> *flink-statebackend-rocksdb*. It doesn't contain arm release.
> Now rocksdb supports ARM from
> [v6.2.2|https://search.maven.org/artifact/org.rocksdb/rocksdbjni/6.2.2/jar]
> Can frocksdb release an ARM package as well?
> Or AFAK, Since there were some bugs for rocksdb in the past, so that Flink
> didn't use it directly. Have the bug been solved in rocksdb already? Can
> Flink re-use rocksdb again now?
