List of decorateKey() Examples

Examples of decorateKey()

org.apache.cassandra.dht.IPartitioner.decorateKey()
Transform key to object representation of the on-disk format. @param key the raw, client-facing key @return decorated version of key
org.apache.cassandra.dht.RandomPartitioner.decorateKey()
org.apache.cassandra.service.IPartitioner.decorateKey()
transform key to on-disk format s.t. keys are stored in node comparison order. this lets bootstrap rip out parts of the sstable sequentially instead of doing random seeks. @param key the raw, client-facing key @return decorated on-disk version of key
