Hi Robert,

Thanks!   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!

Hi Robert,

I see two possible workarounds:
1) You use the unreleased Flink 1.2-SNAPSHOT version. 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

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?
