### Before Creating the Bug Report - [x] I found a bug, not just asking a question, which should be created in [GitHub Discussions](https://github.com/apache/rocketmq/discussions). - [x] I have searched the [GitHub Issues](https://github.com/apache/rocketmq/issues) and [GitHub Discussions](https://github.com/apache/rocketmq/discussions) of this repository and believe that this is not a duplicate. - [x] I have confirmed that this bug belongs to the current repository, not other repositories of RocketMQ. ### Runtime platform environment any ### RocketMQ version develop ### JDK Version jdk8 ### Describe the Bug I found following code in `org.apache.rocketmq.tieredstore.index.IndexStoreService`: ``` @Override public CompletableFuture<List<IndexItem>> queryAsync( String topic, String key, int maxCount, long beginTime, long endTime) { CompletableFuture<List<IndexItem>> future = new CompletableFuture<>(); try { readWriteLock.readLock().lock(); ConcurrentNavigableMap<Long, IndexFile> pendingMap = this.timeStoreTable.subMap(beginTime, true, endTime, true); List<CompletableFuture<Void>> futureList = new ArrayList<>(pendingMap.size()); ... ``` The `pendingMap` is the actual queried index file map, key is create timestamp of the file. But it seemed that `ConcurrentSkipListMap.subMap(K fromKey, boolean fromInclusive, K toKey, boolean toInclusive)` is used wrongly here: the sub map may miss the first index file contains the correct message. ### Steps to Reproduce Enable index build, produce some message, stop production before creating the 2nd index file, query message with time range [a,b] (a > 0), the `pendingMap` should be empty. ### What Did You Expect to See? The query should return correct result. ### What Did You See Instead? Can not find message in tiere storage. ### Additional Context _No response_ -- This is an automated message from the Apache Git Service.
