Shared Data Table?

[Tristan Slominski]

Hello,

I am reading and trying to understand the graphapi v2 source code and cannot find the shared data table mentioned in paper here: http://www.select.cs.cmu.edu/publications/paperdir/uai2010-low-gonzalez-kyrola-bickson-guestrin-hellerstein.pdf

It seems that the shared data table is no longer required, is that the case?

Cheers,

Tristan

Ah. We have progressed quite a bit beyond that paper.
We have a new all distributed abstraction (described on the website) in v2 based on a "gather/apply/scatter" model of update functions. We have an upcoming paper which will describe this system in greater detail.

The new implementation does not require a shared data table, using "syncs" to local variables to accomplish the same effect. We might introduce a DHT data-structure later on as a "support object" for the problems which require it.

Thanks Yucheng,

I found the 2012 paper and read through that: https://www.select.cs.cmu.edu/publications/paperdir/vldb2012-low-gonzalez-kyrola-bickson-guestrin-hellerstein.pdf

Awesome progress.

Ah. We have one more after that. :-) we will send an update in the next month or so once it is ready.
