This is not actually a benchmark, but correctness check (with Spark result).

hmm, let me submit a follow up PR to fix it then..

I thought about this too when reviewing this PR, but decided it is fine since we could re-purpose this workflow in future for both benchmarking and correctness check. It's fine for me if we decide to change it or not.

Does Java version affect this maven cache?

We have os in key but seems Java version isn't there.

I think it doesn't matter that much as most jars are java version agnostic?

And this cache will share the PR build's maven dependency..

Another thing to add: github's cache has quota limit: 10GB. The cached maven dependencies are already quite big(~1GB). If we add the java version to the key, it may create too much maven cache dependencies.

I wonder why we have a - postfix there?

The key is ${{ runner.os }}-java-maven-${{ hashFiles('**/pom.xml') }}, so the restored keys should be a prefix of that key.
See cache action's restore-keys(https://github.com/actions/cache) for explaination:

restore-keys - An ordered list of prefix-matched keys to use for restoring stale cache if no cache hit occurred for key.

The - could be removed, but it would be natural to include that since it's in the prefix of the key.

I wonder why we use this prefix restore key? If hashFiles is different, I think we don't want to restore it, right?

If hashFiles is different, I think we don't want to restore it, right?

For maven dependencies, even if hashFiles is different, we may want to restore it as the previous cache should contains most of needed dependency. mvn will download missing jars automatically.

I opened #132.

@viirya if you have other comments about this PR, you could still add comments in this PR and I would address that in #132.

It's quite slow to build under release profile. We may find a way to speed up rust build.

But it's sufficient for now, we can do that later.

I think it is mostly because we uses lto = "thin".

Can we just restore it using restore action?

Could you point me the link to the restore action? I searched github but didn't find one.

-Prelease to include the release build lib.

And I noticed that the java tests are also executed but they are executed quickly.
