That is not true. Replication is roughly a copy of the diff between the >> master and the slave's index. > > In my case, during replication entire index is copied from master to slave, during which the size of index goes a little over double. Then it shrinks to its original size. Am I doing something wrong? How can I get the master to serve only delta index instead of serving whole index and the slaves merging the new and old index?
