hbase doubts

[Shushant Arora]

1.Is there any max limit on key size of hbase table.
2.Is multiple small tables vs one large table which one is preferred.
3.for bulk load -when  LoadIncremantalHfile is run it again recalculates
the region splits based on region boundary - is this division happens on
client side or server side again at region server or hbase master and then
it assigns the splits which cross target region boundary to desired
regionserver.
