   About the purpose of `PredefinedOptions`:
   
   I guess we want this as a default anyways for all cases. We could simply set 
these always, like the option to create database if missing and to disable WAL.
   ```
   DBOptions
       .setIncreaseParallelism(4)
       .setUseFsync(false)
       .setMaxOpenFiles(-1)
       .setInfoLogLevel(InfoLogLevel.HEADER_LEVEL)
       .setStatsDumpPeriodSec(0);
   
   ColumnFamilyOptions
       .setCompactionStyle(CompactionStyle.LEVEL)
       .setLevelCompactionDynamicLevelBytes(true)
   ```
   
   The remainder are only in `SPINNING_DISK_OPTIMIZED_HIGH_MEM` and should 
pretty much be subsumed by the new memory management. In some sense new memory 
management is the better version of predefined options.
   
   Am I overlooking some use cases?
