Hi ,
I am working on FLINK-33365. I am making good progress; thanks Sergey for your
fabulous feedback. A lot of the query cases are now working with the latest fix
but not all. I think it is pragmatic to revert the lookup join predicate

Piotr, I think the situation is more nuanced than what you've described.
One concern I have is that unaligned checkpoints are somewhat less flexible
in terms of which operational tasks can be safely performed with them --
i.e., if you look at the table in the docs [1], aligned checkpoints support
In line with what David said, after having to explain the (often subtle) issues
around unaligned checkpoints and upgrades while teaching Flink, I would also be
concerned about enabling it by default.
Would it be better to provide more automatic detection of situations where

Thanks for driving this topic. I have two concerns here:

I'm opening this thread to discuss FLIP-414: Support Retry Mechanism in

Currently, there is no retry mechanism for downloading and uploading
RocksDB state files. Any jittering of remote filesystem might lead to a
checkpoint failure. By supporting retry mechan
Hi Ken,
I think the main reason is that currently Kryo is the only generic
serializer in Flink. I'm looking forward to your FLIP of Fury, and we can
continue to discuss this issue there.
If there are no other questions, I will close the voting for this FLIP.
Thank you again.

Hi Piotr,
As a platform administer who runs kilos of Flink jobs, I'd be against the idea
to enable unaligned cp by default for our jobs. It may help a significant
portion of the users, but the subtle issues around unaligned CP for a few jobs
will probably raise a lot more on-calls and incidents

Hi, all.
Considering what Martijn suggested, as a big break, we can directly remove the
old group window agg operator in 2.0
without rewriting it to the new window agg operator.
At the same time, every subtask in this FLIP to align the new and old window
agg operators is almost covered
by the

Thanks for your comment, Yong.
Here are my thoughts on the splitting of HighAvailableServices:
Firstly, I would treat this separation as a result of technical debt
and a side effect of the FLIP. In order to achieve a cleaner interface
hierarchy for High Availability before Flink 2.0, the design de
I agree with @Rui that the current configuration for Flink Client is a
little complex. Can we just provide one strategy with less configuration
items for all scenarios?

Thanks to Piotr driving this proposal!
Enabling unaligned checkpoint with aligned checkpoints timeout
is fine for me. I'm not sure if aligned checkpoints timeout =5s is
too aggressive. If the unaligned checkpoint is enabled by default
for all jobs, I recommend that the aligned checkpoints timeout
Only one strategy is fine to me.
When the multiplier is set to 1, the exponential-delay will become
fixed-delay.
So fixed-delay may not be needed.

Thanks to Yangze driving this proposal!
Overall looks good to me! This proposal is useful for
the performance when the job doesn't need the failover.
I have some minor questions:
1. How does it work with FLIP-383[1]?
This FLIP introduces a high-availability.enable-job-recovery,
and FLIP-383 int
