Hi Guys - I have a question on Vnodes and nodetool repair. If I have configured the nodes as vnodes, say for example 2 nodes with Rf=2.
Questions - * There are some columns set with TTL as X. After X Cassandra will mark them as tombstones. Is there still a probability of running into DistributedDeletes issue ? I understand that "distributeddeletes" is more applicable to application deletes ? * Nodetool repair will ask the neighbour node say node 2 to generate the merkle tree. As I understand, currently the repair introduces 2 compactions. Repairs currently require 2 major compactions: one to validate a column family, and then another to send the disagreeing ranges. Will this be done over the complete data set in the node 2 ? Or only for the range as per Vnodes ? * How does Cassandra do nodetool repair across Data centres ? Assume RF=1 in DC1 and RF=1 in DC2 with total RF = 2 across the two DCs. Thanks, Kanwar
