Intermediate output

2014-01-18 Thread Sebastian Schelter

Hi,

Did we have a way to write out the state of the graph after each 
superstep? I have an algorithm that requires this and I don't want to 
buffer the intermediate results in memory until the algorithm finishes.

you can use giraph.doOutputDuringComputation.

If you use this option, instead of having saving vertices in the end of
application, saveVertex will be called right after each vertex.compute() is
called.NOTE: This feature doesn't work well with checkpointing - if you
restart from a checkpoint you won't have any ouptut from previous
supresteps.

Re: Release date for 1.1.0

I agree, in particular considering that the current patch does not even
apply to trunk.

 Hi,

 I had a look at the list and noticed that https://issues.apache.org/
 jira/browse/GIRAPH-818 (which is based on a research paper) is marked for
 1.1.0.

 Given that this issue proposes to change the programming and execution
 model of Giraph, I don't see it in the scope of the upcoming release.

 The easiest way to start helping with a release would be to
 take a look at the JIRAs in the link I sent to the list a few
 days ago.

 Thanks,
 Roman,

 Hi Roman,

 I will be happy to extend my help in the new release. If you allow, I
 can initiate it and then you can jump in, as and when your time
 permits.
 Thanks

 It is the usual community-driven ASF process. Somebody
 familiar with the project has to step forward as a Release Manager
 and drive the release.

 I did a few months back, but since then I went through a career
 change that made it very difficult for me to find free cycles to
 drive this release. I fully intend to pick up the slack begging
 of  Feb. Given that I think beginning of March should be a
 realistic deadline, but it all depends on the availability of
 the Giraph PMC members to cast votes on the release
 candidate.

 That said, if there's anybody else who would want to
 speed up this release I'd be more than happy to yield.

 By and large though, ASF project typically don't give any
 schedule for future releases. The way to speed it up is
 to join the community, start contributing and volunteering
 as RM.

 Thanks,
 Roman.

 Hi,

 Are there any advances so far on the 1.1.0 release schedule?


 Unfortunately, with my recent job change driving 1.1.0 release dropped
 from my list. I'll try to pick it up back this month. Still very much 
 would
 like to help make it happen.

 Thanks,
 Roman.

I think that after 1.1.0 we could consider this big change, and that there
should be voting for this. It's changing Giraph's shape at the core.

 Hi,

 also think this major change (or enhancement) might be something which
 goes into Giraph in a later release.

 Will there be a voting for such issues?
