Re: HBase table definition and how flexible to change it?

Demai Ni <nid...@...>


thanks for the pointers. 

Neo4j is still running on single server, though there are efforts with data distribution/partition to support true cluster. maybe Neo4j doesn't worry about scalability yet. well, I am not really know much about it either. so should leave to experts to comment on it. 

But scalability is something I care. that why I am looking at JanusGraph.

Hi Demai,
I think it goes all of the way back on when graph theory started.

Maybe one of these links will give you the answer that you are seeking.

I am not sure about Noe4j.  I played with it couple of years ago (when Hadoop was being looked at to being supported).  The problem that I ran into was scalability.  That's why I made the switch to GraphX (Apache Spark) and looking back into JanusGraph.

I hope this help.

Thank You,

Irving Duran

thanks. I just watched the whole presentation. It is pretty helpful to understand tinkerPop. However it doesn't mentioned the storage design about why vertex, edges, and properties should be put together. On another note, does Neo4j keep the three in separated file?

Anyway, appreciate the pointer

This is a good video that I would recommend ->

I would keep your vertex, edges, and properties together.

Thank You,

hi, Guys

new to this form and looking for a few pointers.

I am fairly familiar with HBase, hence plan to use it as the backend. I went through the 'getting-started' tutorial, and have the example up and run. I am looking for a few pointers about the design(of familycolumn, key), and how/why it was designed in such way. And then like to lead to my next questions, is it flexible(and reasonable, beneficial) to store vertex, edge and properties separately?  To do so, which code should I pay attention to? 

Many thanks
