+        return result;
+    }

+    public static class FileRecordsOrError {


I don't think this name is precise enough, but I can't think of a better idea right now.

I carried out an initial pass - thank you for the changes!

                    .orElse(searchInLocalLog::get);
-            result = Right.apply(timestampAndOffsetOpt);
+            result = new OffsetResultHolder.FileRecordsOrError(Optional.empty(),
+                    timestampAndOffsetOpt.isDefined() ? Optional.of(timestampAndOffsetOpt.get()) : Optional.empty());


Can't timestampAndOffsetOpt.isDefined() ? Optional.of(timestampAndOffsetOpt.get()) : Optional.empty() be simplified to just timestampAndOffsetOpt?

Ah, I think I answered my own question - one is a Scala Option and the other is a Java Optional?

Still, maybe something like https://www.scala-lang.org/api/2.13.6/scala/jdk/OptionConverters$.html will simplify this?

Yes, Scala Option and Java Optional is different type

It a good idea, I will address it :)

        val offsetResultHolder = getOffsetByTimestamp
-        offsetResultHolder.maybeOffsetsError = maybeOffsetsError
-        offsetResultHolder.lastFetchableOffset = Some(lastFetchableOffset)
+        offsetResultHolder.maybeOffsetsError(if (maybeOffsetsError.isDefined) Optional.of(maybeOffsetsError.get) else Optional.empty())


Same question

+        this.futureHolderOpt = futureHolderOpt;
+    }
+
+    public OffsetResultHolder(Optional<TimestampAndOffset> timestampAndOffsetOpt) {


Is there a downside to defining a few more constructors which take the concrete type and create an Optional internally? I believe this will save you a lot of Optional.of(new Something() elsewhere, no?

I had opened a PR moving only AsyncOffsetReadFutureHolder in #18095

m1a2st · 2024-12-10T15:16:40Z

@mimaison, thanks for your reminder, this PR will wait for #18095 merge, and I will rebase on it

clolov · 2024-12-11T09:58:58Z

Heya @m1a2st, I reviewed, approved and merged Mickael's PR. If you rebase this PR on top of trunk, I can then review it as well

Hello @clolov, I have been merge trunk into this PR, Thanks for your review :)

clolov

Thank you for the changes and apologies for the delay!

m1a2st · 2024-12-20T12:26:40Z

Thanks for @clolov and @mimaison review.

clolov · 2024-12-20T13:49:58Z

I believe there were failures in trunk after this build. Checking why and issuing a fix

m1a2st · 2024-12-20T13:51:38Z

There is the hotfix
#18284

clolov · 2024-12-20T13:52:42Z

Fyi, I cherry-picked this to 4.0 as it made it easier to then cherry-pick #18321.
