Now this is strange, the index generation and index version is changing with replication.
e.g. master has index generation 118 index version 136059533234 and slave has index generation 118 index version 136059533234 are both same. Now add one doc to master with commit. master has index generation 119 index version 1360595446556 Next replicate master to slave. The result is: master has index generation 119 index version 1360595446556 slave has index generation 120 index version 1360595564333 I have not seen this before. I thought replication is just taking over the index from master to slave, more like a sync?
