Future work on HBase

hbase-todo.txt

CURRENT
- HBASE-50, -6055: Snapshots
- HBASE-5547: HFile backup
- HBASE-4336: Modularization
- HBASE-6087: Add hbase-commons
- 

FUTURE
- wire compatibility for security
- crontab for servers as new CP type
- dynamic reloading cps
- remove cruft
- Accumulo's iterator subclassed as hbase coprocessor
- splits using hosted zk lock
- Auto-merging small tables
- move reference counting from hconnection to manager
- synch-hbase on top of asynchbase
- monotonically increasing ts (rather than wall clock) 
- fix ZK 
      - trackers shouldn't need to check the path of a node update/delete/create, they should just register for the ones they expect and get them all
      - ZKW should have a cleaner way (visitor pattern with static constructor/register?) to add base nodes.
- Automatic cf addition (like accumulo!)
   * no need for a real schema change
 -  asynchronous background memstore flush: part of the crontab stuff?
