-------------------------------------------
Summary: CEP-21 During multi step operations, defer token map
update until completion of final step
Key: CASSANDRA-18419
URL: https://issues.apache.org/jira/browse/CASSANDRA-18419
Project: Cassandra
Issue Type: Task
Reporter: Marcus Eriksson
Updating the token map, used by {{UniformRangePlacement}} to calculate
placements, too early can cause stream plans to be calculated incorrectly. The
eager update of the token map was intended to ensure that subsequent (and
possibly concurrent) range movements would remain compatible with the
operation's end state, but this is not necessary as the affected ranges are
locked and intersecting operations are rejected.
