Keith Turner commented on ACCUMULO-420:
---------------------------------------

According to the following its seems that write are applied in the order that 
they are made.  Also the tserver may need to call sync before reading, but as 
long as it always sees data in order written it should be ok to not call sync.

http://zookeeper.apache.org/doc/r3.1.2/zookeeperProgrammers.html#ch_zkGuarantees

Other places in existing code may need to call sync.

> It may be useful to allow the compact command to specify an iterator to be 
> used for that compaction.  For example if someone wanted to apply a filter 
> once to a table, they could force a compaction with that filter.
