### What problem does this PR solve? Issue Number: close https://github.com/apache/doris/issues/61956 Related PR: https://github.com/apache/doris/pull/63110 Problem Summary: Currently, LSNs are assigned on the BE TabletWriter side during writes, with each node allocating them independently. As a result, replicas may end up with inconsistent LSNs when reading. We are now moving LSN allocation to the sink side so that the same batch of data gets a fixed LSN. At the same time, for publish-conflict cases, we preserve consistency by proactively reading the old LSN instead of allocating a new one. In addition，fix 2 bug about binlog: 1. binlog compaction hasn't get cumulative policy, it will cause DCHECK fail 2. read binlog may receive error, because preaggregation is false. ### Release note None ### Check List (For Author) - Test <!-- At least one of them must be included. --> - [ ] Regression test - [x] Unit Test - [x] Manual test (add detailed scripts or steps below) - [ ] No need to test or manual test.
