    FileUtils.createDirectory(compactionFileLocation);
    int minLevel = Integer.MAX_VALUE;
    // after first migration to be able to drop the sstables back in their original place in the repaired sstable manifest
    for (SSTableReader sstable : sstables) {
        if (minLevel == Integer.MAX_VALUE)
            minLevel = sstable.getSSTableLevel();
        if (minLevel != sstable.getSSTableLevel()) {
            minLevel = 0;
            break;
        }
    }
    return SSTableWriter.create(cfs.newSSTableDescriptor(compactionFileLocation), (long) expectedBloomFilterSize, repairedAt, pendingRepair, cfs.metadata, new MetadataCollector(sstables, cfs.metadata().comparator, minLevel), SerializationHeader.make(cfs.metadata(), sstables), cfs.indexManager.listIndexes(), txn);
}

// log and writer closed during doPostCleanup
@SuppressWarnings("resource")
public static SSTableTxnWriter create(TableMetadataRef metadata, Descriptor descriptor, long keyCount, long repairedAt, UUID pendingRepair, int sstableLevel, SerializationHeader header, Collection<Index> indexes) {
    // if the column family store does not exist, we create a new default SSTableMultiWriter to use:
