> When a node begins bootstrapping, Cassandra recalculates pending tokens for
> each keyspace that exists when the state change is observed (in
> StorageService:handleState*). When new keyspaces are created, we do not
> recalculate pending ranges (around Schema:merge). As a result, writes for new
> keyspaces are not received by nodes in BOOT or BOOT_REPLACE modes. When
> bootstrapping finishes, the node which just bootstrapped will not have data
> for the newly created keyspace.
> Consider a ring with bootstrapped nodes A, B, and C. Node D is pending, and
> when it finishes bootstrapping, C will cede ownership of some ranges to D. A
> quorum write is acknowledged by C and A. B missed the write, and the
> coordinator didn't send it to D at all. When D finishes bootstrapping, the
> quorum B+D will not contain the mutation.
> Steps to reproduce:
> # Join a node in BOOT mode
> # Create a keyspace
> # Send writes to that keyspace
> # On the joining node, observe that {{nodetool cfstats}} records zero writes
> to the new keyspace
> I have observed this directly in Cassandra 3.0, and based on my reading the
> code, I believe it affects up through trunk.
