hi, 社区
版本flink 1.7
我正在尝试从保存点（或检查点）还原flink作业，该作业的工作是从kafka读取->执行30分钟的窗口聚合（只是AggregationFunction，就像一个计数器）->下沉到kafka。
我使用rocksdb和启用检查点。
现在我尝试手动触发一个保存点。 每个汇总的期望值是30（1个数据/每分钟）。 但是，当我从保存点还原时（flink运行-d -s
{savepoint的url}），聚合值不是30（小于30，取决于我取消flink作业并还原的时间）。 但是当作业正常运行时，它将达到30。
我不知道为什么有些数据似乎会丢失？
日志显示``No restore state for FlinkKafkaConsumer''

Subject: inquire about restore from savepoint
Hi Community,
version flink 1.7
im trying to make a flink job restore from a savepoint(or checkpoint), what the
job do is reading from kafka -> do a 30-minutes-window aggregation(just
AggregationFunction, acts like a counter) -> sink to kafka.
i use rocksdb and enabled checkpoint.
now i try to trigger a savepoint manually. the expected value of each
aggregated one is 30(1 data/per minute). but when i restore from a
savepoint(flink run -d -s {savepoint's url}), the aggregated value is not
30(less than 30, depends on the time i cancel flink job and restore). but when
the job run normally, it gets 30.
i don't know why could some data seems to be lost?
and a log shows "No restore state for FlinkKafkaConsumer"
