private void setLastCommittedTranslogGeneration(List<? extends IndexCommit> commits) throws IOException {
    // when opening an existing lucene index, we currently always open the last commit.
    // we therefore use the translog gen as the one that will be required for recovery
    final IndexCommit indexCommit = commits.get(commits.size() - 1);
    assert indexCommit.isDeleted() == false : "last commit is deleted";
    long minGen = Long.parseLong(indexCommit.getUserData().get(Translog.TRANSLOG_GENERATION_KEY));
    translogDeletionPolicy.setMinTranslogGenerationForRecovery(minGen);
