Also, if the data is pushed out to the other nodes before the bootstrapping,
why has data been lost? Does this mean that decommissioning a node results in
data loss?
As I understand it, in the following scenario :
1) Node A has Keys 0-10.
2) Add Node B as a bootstrapping node, Node A is loadbalanced, sheds
keys 5-10 to Node B.
Keys 5-10 are not actually removed from the SSTables on Node A until a
"cleanup compaction" is run. A "cleanup compaction" is a "major
compaction" which also checks to see whether keys still "belong" on this
host.
I don't know whether you have actually experienced data loss, but based
on the above, it should not be possible for you to have.
