Implementation Even though the approach looks simple, the implementation gets tricky because of race conditions. For example, if we autocom- mitted the lookup row. A new insert can immediately find the row, might not have been committed. Similar race conditions exist with various combinations including update and delete operations. To prevent these race conditions, we have to go through an elaborate sequence This means that we cannot guarantee the skew alignment feature will work as expected in certain conditions. This could happen mainly while streaming from replicas with high replication lags, say, due to

This is used, for instance, to know when the Keyspace topology changes (e.g. for
