i have a cluster which contains two CFs. One is a bunch of rows with 10-15 columns per row. the other is an index of those items with only a few rows, but thousands of columns per row. i am noticing that the replication of data between the nodes in the cluster is causing a lot of memtable flushing for the index CF. is this normal? my memtable thresholds are 128M or 1.5m objects. Some of the rows in the index CF have 500k+ columns. Also, this doesn't seem to happen in my dev environment which has a single cassandra node. It also slows down the rate of flush/compact cycles when there is only one node up in the prod cluster.
