Re: Flink batch processing fault tolerance
@Anton, these are the Ideas I was mentioning and I'm afraid I have nothing more to add.

Re: Flink batch processing fault tolerance
Hi, It's the reason why I gave up use Flink for my current project and pick up traditional Hadoop Framework again. 2017-02-17 10:56 GMT+08:00 Renjie Liu : > https://cwiki.apache.org/confluence/display/FLINK/FLIP- > 1+%3A+Fine+Grained+Recovery+from+Task+Failures > This FLIP may help. > > On Thu, Feb 16, 2017 at 7:34 PM Anton Solovev > wrote: > >> Hi Aljoscha, >> >> Could you share your plans of resolving it? >> >> >> >> Best, >> >> Anton >> >> >> >> >> >> *From:* Aljoscha Krettek [mailto:aljos...@apache.org] >> *Sent:* Thursday, February 16, 2017 2:48 PM >> *To:* user@flink.apache.org >> *Subject:* Re: Flink batch processing fault tolerance >> >> >> >> Hi, >> >> yes, this is indeed true.

RE: Flink batch processing fault tolerance
Hi Aljoscha, Could you share your plans of resolving it? Best, Anton From: Aljoscha Krettek [mailto:aljos...@apache.org] Sent: Thursday, February 16, 2017 2:48 PM To: user@flink.apache.org Subject: Re: Flink batch processing fault tolerance Hi, yes, this is indeed true. We had some plans for how to resolve this but they never materialised because of the focus on Stream Processing. We might unite the two in the future and then you will get fault-tolerant batch/stream processing in the same API.

Re: Flink batch processing fault tolerance
Hi, yes, this is indeed true. We had some plans for how to resolve this but they never materialised because of the focus on Stream Processing. We might unite the two in the future and then you will get fault-tolerant batch/stream processing in the same API.
