there are other functions in this library that I would like to use, plus it

We also have a requirement of using Drools in Flink. Drools brings a very
mature and usable business rules editor. And to be able to integrate Drools
into Flink would be very useful.

Hello. Please suggest best method to write data to HBase (stream going from

Hi, I'm using RichMapFunction to enrich data from stream generated from

times to get necessary data from HBase - I believe it makes it

Can I possibly utilize internal Flink’s checkpoint barriers (i.e. like
triggering a custom checkoint or finishing streaming job)?

(well, I also need to somehow distinguish my checkpoint from Flink's
auto-generated ones).
Sorry for being too chatty, this is the topic where I need expert opinion,
can't find out the answer by just googling.

sorry to jumping in, but I think your case is very similar to what I am
trying to achieve in the thread just next to yours (called "Watermarks as

If I'm not mistake, you can use Flink metrics system for operators and get
time of processing event in operator.

In answer Biao said "currently there is no such API to access the middle
NFA state". May be that API exist in plan? Or I can create issue or pull
request that add API?

Hi,
We recently switched to the flink-s3-fs-presto library for checkpointing in
Flink 1.16.0 and we would like to get client-side metrics from the Presto
S3 client (request rate, throttling rate, etc).
I can see that the upstream client from Presto 0.272 already comes with a

It explicitly sets jobmanager.rpc.address to the host IPs.
Am I misconfiguring or misunderstanding something? Is there any way to fix
these errors?
