There is a good comment at the top of StorageService#joinTokenRing which explains the process at a high level: https://github.com/apache/cassandra/blob/cassandra-2.2/src/java/org/apache/cassandra/service/StorageService.java#L791-L803 The method itself is long, but readible and has a series of comments that explain some of the decisions taken and even reference some issues which have been encountered over the years. You can change this value if you really want by passing "cassandra.ring_delay_ms" as a system property at startup. -- ----------------- Nate McCall Austin, TX @zznate Co-Founder & Sr. Technical Consultant Apache Cassandra Consulting http://www.thelastpickle.com
