Sanjay Ghemawat 13e3c4efc6 Fix compactions that could end up breaking a run of the same user key across multiple files. As reported in Github issue #339, it is incorrect to split the same user key across multiple compacted files since it causes tombstones/newer-versions to be dropped, thereby exposing obsolete data. There was a fix for #339, but it ended up not fully fixing the problem. (It checked for boundary problems in the first level being compacted, but not the second). This problem was revealed by Github issue 887. We now adjust boundaries to avoid splitting user keys in both the first level and the second level. PiperOrigin-RevId: 374921082		vor 3 Jahren
