KeyPartition
public KeyPartition()
getId
public int getId()
register
public void register(KeyGroup newKeyGroup)
- TODO During register process not all KeyGroups are necessary, only the
upper, lower one. We can remove all KeyGroups in between to enhance
performance, so we basically don't need any TreeMap for this class, as we
only need to hold the upper, lower bound? It could be problematic, if we
want to decide, if a special KeyGroup is occupied? (E.g. to replicate it
to another node? If we only now the upper, lower KeyGroups, we can't say
if a dedicated key-group is contained or if it is just empty)
Also if we need to broadcast for all KeyGroups, that we are responsible
for it, could be a bit tricky, if we don't know all key-groups
- Parameters:
newKeyGroup
