> Today, the CFs are flushed purely based on the size of the data accumulated 
> in Memtable. If a table has multiple CFs and some CFs are updated at a much 
> slower pace than others, this can prevent a larger number of log files from 
> being deleted. This is because the CF bit in the log header is only turned 
> off when a CF is flushed. A log can't be deleted until all CF bits in the 
> header are cleared. One solution is to add a background flusher that 
> periodically force-flushes every CF.
