Hi Robert, Thanks for the info on 1.2.
I copied over all 4 classes in fs.bucketing. I had to make some changes in my version of BucketingSink. BucketingSink relies on an updated StreamingRuntimeContext that provides a TimeServiceProvider, which the version from 1.1.2 doesn’t. It was easy enough to get around that by changing each occurrence of this: processingTimeService.getCurrentProcessingTime(); to this: ((StreamingRuntimeContext) getRuntimeContext()).registerTimer(currentProcessingTime + inactiveBucketCheckInterval, this); And this: processingTimeService.registerTimer(currentProcessingTime + inactiveBucketCheckInterval, this); to this: ((StreamingRuntimeContext) getRuntimeContext()).registerTimer(currentProcessingTime + inactiveBucketCheckInterval, this); After making those changes, I implemented a custom Bucketer and was able to use my slightly altered version of BucketingSink without any problems. Thanks!

Predicting release dates is always hard. I would say we are in the middle of the development cycle. I can imagine that we have 1.2 released by the end of this year. There is no tool that shows the progress, but I've started a Wiki page recently, tracking which features are probably into which release: https://cwiki.apache.org/confluence/display/FLINK/Flink+Release+and+Feature+Plan and by tracking those features (via JIRA, pull requests, discussions on the dev@ list), you can estimate the progress.

I’ll likely pursue option #2 and see if I can copy over the code from org.apache.flink….fs.bucketing. Do you know a general timeline for when 1.2 will be released or perhaps a location where I could follow its progress? Thanks again!

From time to time, there are some unstable commits in that version, but most of the time, its quite stable. We provide nightly binaries and maven artifacts for snapshot versions here: http://flink.apache.org/contribute-code.html#snapshots-nightly-builds 2) If that's too risky for you, you can also copy the code of the new (1.2-SNAPSHOT) bucketer from master into your project. The Apache license allows you to copy the code into your own projects, and I think the bucketer code doesn't rely on any features / APIs added in 1.2-SNAPSHOT, so you can probably run the new code on Flink 1.1 as well. I hope that helps, Regards, Robert On Wed, Oct 12, 2016 at 2:10 PM, <robert.lancas...@hyatt.com<mailto:robert.lancas...@hyatt.com>> wrote: Hi Flinksters, At one stage in my data stream, I want to save the stream to a set of rolling files where the file name used (i.e. the bucket) is chosen based on an attribute of each data record. Specifically, I’m using a windowing function to create aggregates of certain metrics and I want to save that data in a file with a name that identifies the window. I was planning to write my own bucketer for this, but in version 1.1.2 the Bucketer interface doesn’t allow for the element being processed to be passed to the relevant methods (e.g. getNextBucketPath and shouldStartNewBucket). I see that this is taken care of in 1.2, but since that isn’t available yet, can anyone recommend a workaround? Alternatively, is there a way to have the DateTimeBucketer use assigned timestamps instead of system time? ________________________________ The information contained in this communication is confidential and intended only for the use of the recipient named above, and may be legally privileged and exempt from disclosure under applicable law.
