Dear All,
Any update regarding Graph Streaming, I want to update, i.e., add vertices
and edges after creation of graph.
Any suggestions or recommendations to do that.
Thanks,

Any updates on GraphX Streaming? There was mention of this about a year ago,
but nothing much since.
Thanks!

Hi All,
Thanks for your answer.
Regarding GraphX streaming:
- Is there an issue (pull request) to follow to keep track of the update?
- where is possible to find description and details of what will be
provided?
Thanks for your help and your time to answer my questions

As Matei said, there's currently no support for incrementally adding
vertices or edges to their respective partitions. Doing this efficiently
would require extensive modifications to GraphX, so for now, the only
options are to rebuild the indices on every graph modification, or to use
the subgraph
I just meant that you call union() before creating the RDDs that you pass to
new Graph(). If you call it after it will produce other RDDs.
The Graph() constructor actually shuffles and “indexes” the data to make graph
operations efficient, so it’s not too easy to add elements after. You could
a
I would assume that, regardless of the efficiency of such an operation, any
method of adding or removing vertices would need to result in a new graph,
since graphs in GraphX are supposed to be immutable.
It sounds like what you probably want is an efficient
union/subtract/whatever that operates on
Hi All,
Is somebody looking into this?
I think this is correlated with the discussion "Are there any plans to
develop Graphx Streaming?".
Using union / subtract on VertexRDD or EdgeRDD leads on the creation of new
RDD but NOT in the modification of the RDD in the graph.
Is creating a new graph th
Hi Matei,
Could you please clarify why i must call union before creating the graph?
What's the behavior if i call union / subtract after the creation?
Is the added /removed vertexes been processed?
For example if i'm implementing an iterative algorithm and at the 5th step i
need to add some ver
Or Titan on hbase, so you could try reading graphs directly via custom io
formats
Does this suggest value in an integration of GraphX and neo4j?

Good catch, I’ve fixed those.

Quick side-note on that page, Matei: Several versions up to and including
0.9.0 are still marked as "unreleased" in JIRA. Dunno if that's intentional
(or if it matters any).

You can create a ticket, but note that real-time updates to the graph are
outside the scope of GraphX right now. It’s meant to be a graph analysis
system, not a graph storage system. I’ve added it as a component on
https://spark-project.atlassian.net/browse/SPARK.

Hi Matei,
Thanks for the quick response. Is there a plan to support this? Any ticket I
can follow? I don't see a GraphX component at
https://spark-project.atlassian.net; is there a different bug database for
GraphX?
Thanks.

Right now there isn’t. It’s meant for analysis once you have a graph. If you
just need a few vertices at the beginning you could add them to the vertex and
edge RDDs using RDD.union() before creating a Graph.
