<i>&gt; To defend against duplicate messages, we employ an embedded key&#x2F;value store - namely, RocksDB. RocksDB contains an in-memory Bloom Filter that we use to check for, and ignore, previously applied messages.</i><p>Wait, what? Can anybody explain this part? I don&#x27;t understand how you could use a bloom filter for this. A bloom filter will have false positives by definition. When a false positive is encountered, the message would be ignored even though it has not been previously applied? I&#x27;m guessing the explanation is missing something as this seems a very straight forward issue to miss.
