Re: disable compaction if all data are read-only?

You still need compaction. Compaction is what organizes your data into levels. Without compaction, every query would have to look at every SSTable. Also, due to commit log rotation, your memtable may get flushed from time to time before it is full, resulting in small SSTables that would benefit
