ConclusionĪnd that’s it! You can read the source for the API handler for GetAvailablePackagesummaries which is kept quite simple, as well as the more substantial code for the fan-out and fan-in with go channels. When the next request from the client includes this token, the API handler passes each offset to each plugin with when setting up the fan-out, so that each plugin is able to begin at the correct point. In reality, it’s just a JSON-encoded string such as can be seen in the above screenshot of the debugging console.
It is not overly resource intensive since each plugin is only fetching its own next page of items when required, and importantly, each step is comparatively simple to reason about on its own.įinally, to ensure that the client can request a subsequent page of results and continue to receive the correct, ordered, aggregated result from each of the plugins, the aggregated API returns an opaque nextPageToken back to the client. With that, the fan-in is able to pass the correct number of aggregated individual items back to the API handler, in order, from the respective plugins which themselves fetch in parallel. The comparison used to select the minimum is just a string comparison of the related Kubernetes resource Metadata.Name, since this is what the Kubernetes API server returns. This routine will continue to loop until it has either sent the requested number of items back to the API handler, or it has exhausted all items from all plugins. Sends the selected minimum value down its own channel back to the handler.Infinifactory presents players with a set of quite complex challenges to solve, where the objective is to place various interactive blocks in order to complete given tasks.
INFINIFACTORY INTERFACE SERIES
Selects the minimum item from those latest available from each channel, Infinifactory If you prefer puzzle games, then there’s also one for you on the list Infinifactory turns factory management into a series of increasingly difficult challenges.Ensure it has the latest item from each channel available for comparison,.Once data is coming in on the input channels, the fan-out/fan-in routine does the following in a loop: How does this help the API handler aggregate ordered data from the configured plugins? The Fan-In It’s important to note that each channel here is unbuffered, so the go-routine created for each plugin will only fetch the next page of results when the current results are exhausted from the channel, and so does only the minimum required amount of work.Īt this point, the fan-out/fan-in routine has three channels of data. This allows the fanned-out requests to the plugins to be handled concurrently, looking something like: When a request is received by the core packages API handler for a page of 20 available packages, the handler fans this request out, creating a go-routine for each plugin, where each go-routine sends the results back to the fan-out routine, one at a time, each plugin via its own channel.
INFINIFACTORY INTERFACE UPDATE
It's that accessibility that makes Infinifactory special: not only is it clever, but it shares its cleverness with the player.In Kubeapps, we have a pluggable API server for supporting different package formats for Kubernetes, allowing users to install, update and delete packages on a cluster with a consistent UX experience across different packaging systems.īut how do we handle returning a page of ordered, aggregated available packages from different plugins in a consistent and extensible way, without the client needing to care how the result is composed? The best Infinifactory solutions blow my mind, but I'm happy with my own ones too. This is the most generous game Zachtronics has made, opening up SpaceChem's lofty problem-solving up to anybody who can place blocks without sacrificing too much intellectual headroom in the process. It's nice to be able to finally give Infinifactory the outright recommendation it warranted earlier in the year. It's appropriate, then, that Infinifactory allows you to output a gif of your creations at the touch of a button (these have been upgraded in a recent patch, too) and that, for those who want to take things further, there's the option to create and share user-generated puzzles via the Steam Workshop. It's the videogame equivalent of those incredibly compulsive looping gifs of factory processes, but you made it-and the pride you experience in coming up with a solution feels 'earned' in a way that it does in few other games. There's a tremendous satisfaction to watching a machine that you've slaved over diligently follow your orders. The genius of Infinifactory is not that it's a very well-designed puzzle game: it's that it makes you feel like a talented designer too.
