kandi X-RAY | dGraph Summary

dGraph is a JavaScript library typically used in User Interface, Animation applications. dGraph has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

Create layered directed graphs in SVG with a few lines of JS in a beautiful and compact layout. The library is based on a modified [Sugiyama algorithm] "Kozo Sugiyama"). The data feed into the graph library needs to be a node list with its corresponding adjacency list. Each node object in the list is expected to have at least the two properties label and layer. See the two provided example pages [example-simple.htm] example-simple.htm) and [example-complex.htm] example-complex.htm) for more information. ![example-complex] graph/resources/example-complex.gif "complex example of a graph drawing").

            To model a pivot table that is only a linking pivot table holding no additional information, then you model it as you did above. However, if your pivot table contains additional information regarding the relationship, then you will need to model it with an intermediate linking type. Almost the same idea as above. I prefer these linking types to have a name describing the link. For instance I named it in this case Stock but that name could be anything you want it to be. I also prefer camelCase for field names so my example reflects this preference as well. (I added some search directives too)

            What a well-asked first question. Welcome to Stackoverflow.

            Your code is fine. You are running into a limitation of networkx, which does not keep track of the arc of the edge when labelling edges. Instead, it places edge labels on a straight line between the two nodes; by default, it chooses the center of that straight line. This has two consequences for your plot:

            1. the edge labels are slightly offset w.r.t. your edge paths, and
            2. labels on bi-directional edges are plotted on top of each other.

            There is no solution for the first issue; however, you can work around the second issue by specifying the argument label_pos to anything other than 0.5. For example, changing your code to

            The back-end (DGraph GraphQL hosted server https://slash.dgraph.io/) requires a ‘namespace’ for the claims I want it to use but all of the claims in my token are at the root of the payload.

            You'll need to create your namespace as one claim within the authorization server, then add each of the claims within the namespace inside of that claim's value inside of {} as if you were writing JSON.

            Value for copy paste simplicity {"one":"one", "two":"two", "username": appuser.userName}

            What is using so much memory on an idle linux server? Comparing output of "htop" and "ps aux"
            Asked 2021-Jan-02 at 20:49

            I am trying to understand and compare the output I see from htop (sorted by mem%) and "ps aux --sort=-%mem | grep query.jar" and determine why 24.2G out of 32.3G is in use on an idle server.

            The ps command shows a single parent (not child process I assume):

            ANSWER

            Answered 2021-Jan-02 at 20:49

            The primary difference between htop and ps aux is that htop shows each individual thread belonging to a process rather than the process only - this is similar to ps auxm. Using the htop interactive command H, you can hide threads to get to a list that more closely corresponds to ps aux.

            In terms of memory usage, those additional entries representing individual threads do not affect the actual memory usage total because threads share the address space of the associated process.

            RSS (resident set size) in general is problematic because it does not adequately represent shared pages (due to shared memory or copy-on-write) for your purpose - the sum can be higher than expected in those cases. You can use smem -t to get a better picture with the PSS (proportional set size) column. Based on the facts you provided, that is not your issue, though.

            In your case, it might make sense to dig deeper via smem -tw to get a memory usage breakdown that includes (non-cache) kernel resources. /proc/meminfo provides further details.

            Welcome to Stack Overflow!

            To get your code working locally with the docker "standalone" version of DGraph I had to change 2 things:

            • use port 9080. The container exposes 3 ports: 8000, 8080, 9080. Using 8080 or 8000 I get the same error you mentioned.
            • use the v2 imports. Not sure which version of DGraph server you are running, so you might not need to do this. But in case you have a new server you need these imports:

            It looks to me like you could be returning the appropriate data in your user resolver, with one exception: when Absinthe goes to resolve the fields for each user, the default resolver only looks for the fields as atom keys. When it can't find :uid, :email, or :name in the parent maps, it returns nil.

            You could convert the result to have atoms as keys. One option if you want to go that route would just be to map over each user and explicitly copy what you want.

            3. Delete all triples for a given node

            Now i'd like to delete all triple for nodes of a given type. I assume this is done by some kind of combination of a query that selects the nodes for the the given type and then a mutation for each of these nodes. I couldn't find an example for this in the tutorial.
