1 => {name: "John Doe", phone: "5555555"} 2 => {name: "Jane Doe", phone: "6666666"} # to remove the phone number we can replace the value with a new message 1 => {name: "John Doe"} # to completely delete key 1 we can send a tombstone record 1 => null # but until compaction runs (and some other conditions are met), reading the whole topic will get all three values for key 1, and the old values are still retained on disk. |
