The following is the source code, I do not understand

/**
 * File WAL manager.
 */
public class FsyncModeFileWriteAheadLogManager extends GridCacheSharedManagerAdapter implements
IgniteWriteAheadLogManager {

/**
 * File WAL manager.
 */
@SuppressWarnings("IfMayBeConditional")
public class FileWriteAheadLogManager extends GridCacheSharedManagerAdapter implements IgniteWriteAheadLogManager
{


What is the impact of this error? Can I use this cluster as a production environment?


Please help me, thank you
