> Keith Turner wrote up a nice description of the BatchWriter on the gora mailing list. I think it deserves to be in the BatchWriter documentation:
> {quote}
> When the user creates a
> BatchWriter to write to Accumulo they specify how much memory and how
> many threads it should use. As the user adds mutations to the batch
> writer it buffers them. Once the buffered mutations have used half of
> the user specified, the mutations are dumped into the background to be
> written by a thread pool. If the user specified memory completely
> fills up, then writes are held. When a user calls flush, it does not
> return until all buffered mutations are written.
