Hello. I have set up test cluster of 2 DCs with 1 node in each DC. In each config I specified 256 virtual nodes and chosed GossippingPropertyFileSnitch.
For node1: ~/Cassandra$ cat /etc/cassandra/cassandra-rackdc.properties dc=DC1 rack=RAC1 For node2: ~/Cassandra$ cat /etc/cassandra/cassandra-rackdc.properties dc=DC2 rack=RAC1 When I call "nodetool status", it shows not 100% ownership of tokens for each DC: :~/Cassandra$ nodetool status Datacenter: DC1 =============== Status=Up/Down |/ State=Normal/Leaving/Joining/Moving -- Address Load Tokens Owns Host ID Rack UN 172.16.0.1 97.43 KB 256 51,5% 7ffd2432-46c9-443c-aa0c-8bfd960d2acc RAC1 Datacenter: DC2 =============== Status=Up/Down |/ State=Normal/Leaving/Joining/Moving -- Address Load Tokens Owns Host ID Rack UN 172.16.0.2 91.78 KB 256 48,5% 93d3bdbf-8625-4e54-8c7c-087fbfe419f5 RAC1 I thought that each datacenter has 100% coverage of token range. What does the value in "Owns" field mean and how it affects a replication (for exaple, with replication factors DC1:1, DC2:2)? Thanks in advance, Sergey Naumov.
