How to resolve trace_filter does not exist when deploying balancer sub-graph in graph-node?

Azure Cosmos graph db supported Gremlin and Tinkerpop version

QUESTION

HTML CSS JS Graph Visualization

Asked 2021-Mar-24 at 11:41

I'm trying to draw below structure using HTML CSS JS/JQuery. It's actually a UI for a kind of path tracer where I'll change the color of edges and nodes to indicate visited nodes and edges.

This is drawn on canvas and is my target to achieve. Initially it will show like this, and after running some algorithm, some nodes end edges will be colored differently to show the path travelled.

What I've tried: Initially I've checked some libraries like GoJs but their graphs were either changing their layout on each refresh(which will cause me problem when updating the node colors) OR they were very complicate for the newbie me. So I tried to assemble one from scratch with below steps:

(1) From the above image, first I've extracted the coordinates of nodes using mobilefish.com and stored them in a list. Used them to position nodes on my page. (Although nodes are visible but I'm having problem in scaling them down relative to the section on my page where I'm presenting the graph.)

(2) created a node template in HTML and used Jquery to insert several copy (with unique dynamic id) in a div(later I changed this container to svg because drawing edge lines was tough).

Here is an example of what I think you want to do: https://gojs.net/latest/samples/distances.html

Nodes do not have to move if you do not want them to as you make changes, as shown when you click on the button below the diagram. To prevent layout from happening when you add or remove nodes or links, set the Layout.isOngoing property to false on the Diagram.layout.

Geth node doesn't have support trace_filter method so far. For some subgraph like balancer-subgraph, when try to deploy it to graph-node, it'll try to call this method trace_filter. but as geth node didn't have API support, graph-node faces error for this

Reference: Geth JSON-RPC doesn't have trace_filter API support. Follow this link to find the supported APIs by geth node.

To fully support graph-node need to use parity node. This has supported APIs by parity

QUESTION

Azure Cosmos graph db supported Gremlin and Tinkerpop version

Asked 2020-Feb-10 at 20:10

I'm having trouble finding what Azure Cosmos DB supports in using npm gremlin and Tinkerpop. https://www.npmjs.com/package/gremlin The gremlin package makes no reference to client.submit scripts, however, the Azure Node.js sample code uses submit.
https://github.com/Azure-Samples/azure-cosmos-db-graph-nodejs-getting-started/blob/master/app.js

Also, when I use tinkerpop features like filter, elementMap, etc. in a client.submit, it throws an error that it can't find it. g.V().elementMap('age') This suggests to me that only certain Tinkerpop features work inside client.submit. I'm using the latest http://tinkerpop.apache.org/docs/3.4.4/reference/

I don't get any response from Azure on this topic. Can anyone shed some light on how to use the latest gremlin and tinkerpop with Azure Cosmos DB? If not latest, which specific versions of each are supported?

Thanks, Donnie

I'm not an expert on CosmosDB but I don't think they support any specific version of TinkerPop but rather a subset of the available functions (though they have been steadily moving toward more full fledged support since release). Your best bet would be to look at the Gremlin steps they have documented as the ones they support and only use those. That list of steps can be found here.

Note that there have been times where CosmosDB users here in Stackoverflow have come to find that there are supported steps not listed on that page, so giving a step a try if you really need it, even if not listed there, might actually work for you.
