Hello, we have a business scenario. We have a real-time process to calculate
how much red envelopes should be given to them for each transaction. For
example, if a customer pays $100, we will give him a rebate of one thousandth.
We currently use flinksql to Realize this function, but we found
Thanks for the response Weihua.
I am using flink v.15.2. I am unable to understand how I should be starting
the jobmanager without the job so that it can poll HA store and start the
job.
Since the current method of running the script standalone-job.sh requires a
job at start. If I provide the same
Hi, yxy,
I think this scenario could be resolved by a lookup join or a UDF. We can
store the ratio in the mysql table. Then we could read it by a lookup join

I tried with flink v1.15.2 with the flowing example, but can't reproduce.
Could you provide the full start command?
1. ./bin/standalone-job.sh
Hi, yangxueyong,
If the ratio will not be modified frequently, we could set a long TTL for
the cache in the lookup table to reduce the frequency of reading, or put a
cache in the UDF.
If you need the exact ratio when the data arrives, we have to read it from
the remote storage each time we get new
I can't really find any examples / docs for Flink's AsyncTableFunction and
I have a hard time getting it to work.
Is there any example you can share that just takes as input a String key
and outputs lets say a record (returned by the lookup?)
Also is not clear to me how the async happens internally
