Java 如何使用ApacheFlink在这个avro模式中应用过滤器

大家好，我正在反序列化Avro Kafka的消息，如下所示：

FlinkKafkaConsumer<String> consumer = new FlinkKafkaConsumer("conekta.public.person",
     new KafkaGenericAvroDeserializationSchema("http://localhost:8081"), kafkaProps);

我如何应用过滤器获取flink consumer上id<258的所有记录

我是阿帕奇·弗林克的新手

任何帮助都将不胜感激

谢谢

当希望流结束时，可以覆盖KafkaGenericAvroDeserializationSchema上的

布尔isEndOfStream（GenericRecord nextElement）

，以返回true
