我有一个Flink星系团。我启用了压缩过滤器并使用状态ttl。但是rocksdb压缩过滤器不能从内存中释放状态。
我的flink管道里有大约300张唱片
我的状态ttl配置：

@Override
public void open(Configuration parameters) throws Exception {
    ListStateDescriptor<ObjectNode> descriptor = new ListStateDescriptor<ObjectNode>(
            "my-state",
            TypeInformation.of(new TypeHint<ObjectNode>() {})
    );

    StateTtlConfig ttlConfig = StateTtlConfig
            .newBuilder(Time.seconds(600))
            .cleanupInRocksdbCompactFilter(2)
            .build();

    descriptor.enableTimeToLive(ttlConfig);

    myState = getRuntimeContext().getListState(descriptor);
}
