> Currently flushing of timeline writes is not really handled. For example, 
> {{HBaseTimelineWriterImpl}} relies on HBase's {{BufferedMutator}} to batch 
> and write puts asynchronously. However, {{BufferedMutator}} may not flush 
> them to HBase unless the internal buffer fills up.
> We do need a flush functionality first to ensure that data are written in a 
> reasonably timely manner, and to be able to ensure some critical writes are 
> done synchronously (e.g. key lifecycle events).
