Graphviz and Dot
Hi folks I have a Sinatra application that uses Graphviz and Dot. I'm guessing that it won't be possible to host this on Heroku? If not, does anyone know of a good home where I could host it? I'd like something with the simlicity and scalability and general awesomeness that Heroku gives us.

Re: Graphviz and Dot
Hi, Can you provide some links to the libraries you're seeking to use, and perhaps some info on binary dependencies? It's possible we can add support for these to our Dyno environment, but I'd have to know a bit more first.

Re: Graphviz and Dot
dot (and nice)is a command line app. Graphviz is the package/library name. It is in macports and basically all distributions. Most (all) ruby libraries are wrappers for the command line. The downside is it produces graphics. So it needs all the libraries to produce text in png, jpg, svg, pdf, bmp, ps, ... Think it requires X, truetype, and *lots* of others. May be possible to reduce the number of outputs by only supporting jpg, png, and svg. Do all browsers (iPhone, phones) support svg? Never really used it but looks cool. Seems to have the least number of dependencies. And with css would be easy to make output good looking. Windows outlook on coworkers computers don't do well with png so I used jpg for them.

Re: Graphviz and Dot
Hi Morten Thanks for the fast reply :) I'm no linux build-master, so not sure about determining the dependencies. Installing Graphviz on a linux server of mine (using apt- get install graphviz) yeilded quite a large result (see end of this message). I fear it's a chunky beast :-( But maybe I've misread the facts. I only use a part of GraphViz (http://www.graphviz.org) called dot -- an single binary.

Re: Graphviz and Dot
Tobes. I too would love to see graphviz on heroku. Basically it is a program that writes text and lines to a png. So it needs to have good text support. I think this is the part that has so many libraries. It also supports so many formats that it needs libraries for all of them. These are icing on the cake. Sure seems there are 2 parts to the library. 1. Determine what the thing looks like 2. create the graphics. Funny thing, most people want #1 The part that is such a bear is #2. (Wonder if you could extract #1 and just use imagemagic to do #2 or something) --K On Apr 17, 2009, at 3:05 PM, Tobes wrote: Keenan, thanks for the heads up.

Re: Graphviz and Dot
Again, thanks for considering all this. Keenan, I'll keep searching, and if I can delegate #2 (create graphics) to something like imagemagic then that would be awesome. I actually started out playing with ImageMagick, knowing you guys supported it, but couldn't find a way of handling the layout (#1) neatly. Another scenario that I could run with would be: putting the Graphviz services on another cluster/machine, and then having a queue or bus to distribute that work out from Heroku.

Re: Database layer autoscaling?
Hi Marc, Unlike the web tier, we don't believe it's possibly to do horizontal +infinite auto-scaling of SQL databases. That is reserved for distributable document databases like CouchDb, MongoDb etc that will undoubtedly become an important part of the web application space in the near future. For now, Heroku provides seamless vertical scaling of our SQL database layer. It'll go from a shared db environment - like you see in our free beta - up to a dedicated server based on the largest high-cpu instance EC2 has to offer. Throughout all our tiers redundancy and failover is fully managed by our infrastructure, and you don't have to worry about it. Upgrading between the tiers is seamless and invisible as well. Hope this answers your question. We should be releasing more public info on this within a week or two. Best, Morten On Apr 13, 2009, at 3:36 PM, marcdmarc wrote: Hello, I am intrigued by the heroku value proposition. From the online information regarding heroku and it's capabilities, it is a little unclear if heroku solves the problem of auto scaling the database layer. I notice there is an option for providing database replication. I assume this would be in a master slave type setup? What is to be done if there needs to be more than one slave? Or is this totally handled by heroku's infrastructure wherein heroku can scale the database layer infinitely without the developer ever having to worry about setup and optimizing the databases themselves. If there is anyone who can shed light into the topic about how heroku handles db scaling and if this is left to the developer to handle or if heroku is capable of handling 100% of this process, I would really appreciate it.

Re: Graphviz and Dot
Hi Tobin, Just a fellow heroku user like you. GraphViz does such great stuff. The layout is just great. Display is not as nice as something like OmniGraffle, but the layout is superior. (I think OmniGraffle hired the guy from ATT, and is doing great stuff merging the concepts between the two products. But it still has a little way to go. e.g.: it doesn't support different layouts for different subgraphs which is something that GraphViz does wonderfully) But I do wonder what it would be like to separate the layout from the generation. Of course if that layout would be best done in ruby. :) Looking at the dependencies, wonder if they use TCL to do that work. --Keenan On Apr 17, 2009, at 6:31 PM, Tobes wrote: Again, thanks for considering all this.

Re: Graphviz and Dot
Good call Ryan, Never thought imagemagick. That probably includes most of the dependencies that GraphViz would need. Also pruning down the supported formats to those 3 would probably prune down the additional libraries needed much further. Also, thanks Tobes for asking the question.
