Describe the bug (actual behavior)

We have several compacted (cleanup policy: compact) topics in our clusters, when we try to load messages in any of them using the "oldest" filter, it takes a significant amount of time to load (around 1 minute or more). Worthy to note that this doesn't occur when selecting the "newest" filter.

The topic size is around 17MB.

We monitored the CPU and memory of kafbat and increased it significantly in efforts to get a faster load time, but it didn't help. The app logs and console logs looks normal

We have significantly larger topics that are not compacted and they load the messages instantly, regardless of which filter.

Expected behavior

messages in compacted topics are loaded faster, like normal topics that have delete cleanup policy

Your installation details

running the latest main 1196f9f docker image deployed in EKS as a normal k8s deployment without helm.

Steps to reproduce

create a compacted topic and load it with some significant data

Similar problem we noticed: for compact topics, oldest is working fine for us. But when we switched to use newest, it took forever to load.

@Haarolean this should be fixed due to #406

@wanisfahmyDE so does it work now?

[wanisfahmyDE]

no it doesn't, I created the issue when we were running already on ghcr.io/kafbat/kafka-ui:main

[xuyuanz]

yes switched to use kafka-ui:main. Now it loading forever for "oldest" messages.
