I am saving JSON messages in the topic. And with consumer I need to get only one message. For example get message with JSON node: code = 123 ---- 2020-07-10 23:15:15 UTC - Ali Ahmed: there is no filtering of messages in pulsar at the broker level you have read messages and filter them on client side or you can look into pulsar function to generate a filtered topic ----
