Hi, I am using Apache Ignite 1.9 in the embedded mode, I am using it as an inmemory data grid. I want to use the mode Partitioned Mode cache and I am trying to gather usage information.
- The backups which is mentioned in the documentation, how do I define which node is the primary node and which node is the backup node. - I will have a four node cluster in two data centers , is it normal to think each data center would have one primary node and one backup node. What would happen in the scenario that the primary node on one dc cannot reach the primary node on the other dc? - I assume that org.apache.ignite.spi.discovery.tcp.TcpDiscoverySpi is to be used for the dsicoverySpi property even for Partitioned Caches. Are there special properties that should be filled in for the partitioned cache except for addresses and ports? - Most of the caches I am using is using uuid as keys , in that case how would affinity collocation of the keys work? Unfortunately I cannot change the key structure in a short notice. Thanks and Regards, Saby
