Having looked at the proposed set of methods to remove I've noticed that
some of them are actually annotated with @Public. According to our
stability guarantees, only major releases (1.0, 2.0, etc.) can break APIs
with this annotation. Hence, I believe that we cannot simply remove them
unless the c
Hi all,
@Klou Nice write up. One comment I have is I would suggest using a
different configuration parameter name. The way I understand the
proposal the BATCH/STREAMING/AUTOMATIC affects not only the scheduling
mode but types of shuffles as well. How about `execution.mode` ? Or
`execution-runtime-
Hi Yun and Dawid,
Dawid is correct in that:
```
BATCH = pipelined scheduling with region failover + blocking keyBy
shuffles (all pointwise shuffles pipelined)
STREAM = eager scheduling with checkpointing + pipelined keyBy shuffles
AUTOMATIC = choose based on sources (ALL bounded == BATCH, STREAMIN

Hi Lei,
you can check how the FlinkFixedPartitioner [1] or
Tuple2FlinkPartitioner [2] are implemented. Since you are using SQL
connectors of the newest generation, you should receive an instance of
org.apache.flink.table.data.RowData in your partitioner.
You can create a Maven project with a
Hi Forideal,
luckily these problems will belong to the past in Flink 1.12 when UDAF
are updated to the new type system [1]. Lists will be natively supported
and registering custom KryoSerializers consistently as well.
Until then, another workaround is to override getAccumulatorType() and

Being able to optionally fire registered processing time timers at the end
of a job would be interesting, and would help in (at least some of) the
cases I have in mind. I don't have a better idea.

Hi Zhinan,
For the time to detect the failure, you could refer to the time when
'fullRestarts' increase. That could give you information about the time of job
failure.
For the checkpoint recovery time, there actually exist two parts:
1. The time to read checkpoint meta in JM. However, this
Hello folks,
We are using flink 1.9 SQL API and we are NOT using blink planner. Our
platform users express their flink jobs as SQL queries. We currently have a

Hi Lei,
If you want to write your custom partitioner, I think you can refer to the
built-in FlinkFixedPartitioner[1]

Hi, Lei ~
You may need to implement the abstract class FlinkKafkaPartitioner and then use
the full class name as the param value of the option ‘sink.partitioner’.
FlinkFixedPartitioner[1] is a good example there.

Hi Youngwoo,

Currently, SQL client uses legacy types for the collect sink, that
means `TIMESTAMP

you can refer to [1] to find the supported types, and there is a pr [2] to
fix this.

Writing to database is the bottleneck when too much message is sent to kafka

Hi Yun,
Thanks a lot for your help. Seems hard to measure the checkpointing restore
time currently.
I do monitor the "fullRestarts" metric and others like "uptime" and
"downtime" to observe some information about failure recovery.
Still some confusions:

hi,
We have a flink job platform which will resubmit the job when the job
failed without platform user involvement. Today a resubmit failed because
of the error below, I changed the akka.Frameszie, and the resubmit succeed.
My question is, there is nothing change to the job, the jar, the program,
