Pulsar is a Top 10 Apache Software Foundation project and has a vibrant and passionate community and user base spanning small companies and large enterprises.

Topics (i.e., partitions) are divided among Pulsar brokers. A broker receives messages for a topic and appends them to the topic’s active virtual file (a.k.a ledger), hosted on the Bookkeeper cluster. Brokers read messages from the cache (mostly) or BookKeeper and dispatch them to the consumers. Brokers also receive message acknowledgments and persist them to the BookKeeper cluster as well. Brokers are stateless (don't use/need a disk).

I'm sure many of you have a folder full of random screenshots, bookmarks and files for commonly used components you work with. Baptiste and I wanted to create a simple resource with custom, easy to identify illustrations, so that's what we did. It started off being a lot smaller in scope, and ballooned into over 300 pages.

So far the book covers 130 different individual components and boards, and we plan on adding more as the project goes on. There's a full list of everything included on Pinouts.org

We always kept in mind the idea of this being a quick reference, as opposed to a 5000+ page super technical document, so we've intentionally kept things uncomplicated. That being said though, if you do need to find more information about a particular pinout, we have included links at the top of each page. Go to those addresses and they will redirect to any corresponding wikis, datasheets or specifications we could find.

It was originally designed to be a physical book, but we realised it made more sense to be downloadable, as we can keep updating it regularly. We may do on-demand printing down the road once we've fleshed things out though.

We hope you like this and find it useful. If you want to support the project we made some nice tshirt designs based off the illustrations in the book. They're also on the site if you're interested.

Its features include multi-tenancy with resource separation and access control, geo-replication across regions, tiered storage and support for six official client languages. It supports up to one million unique topics and is designed to simplify your application architecture.

A Pulsar client contains a consumer and a producer. A producer writes messages on a topic. A consumer reads messages from a topic and acknowledges specific messages or all up to a specific message.

This includes separate sections for Adafruit, Arduino, and Raspberry Pi, and then a large range of other random SBCs, like Tinker Boards, Beaglebones, Banana Pi, Odroid and others.

Hey everyone, hope you're doing well. Here is a project that my friend Baptiste and I have been working on for quite a while, and we're glad to be finally showing you.

Pulsar and BookKeeper use Apache ZooKeeper to save metadata coordinated between nodes, such as a list of ledgers per topic, segments per ledger, and mapping of topic bundles to a broker. It’s a cluster of highly available and replicated servers (usually 3).

The design is split into 2 main parts. On the left page there is a simple illustration of each component. We tried to make these as easily recognisable as possible, and since it's a PDF, you can zoom right in when needed. Then on the opposite page is the corresponding table containing information on the pins, and if available, any other pertinent info like power requirements etc.

Apache Pulsar is an all-in-one messaging and streaming platform. Messages can be consumed and acknowledged individually or consumed as streams with less than 10ms of latency. Its layered architecture allows rapid scaling across hundreds of nodes, without data reshuffling.

This is really only the beginning, so please bare with us. We looked at everything a million times over but we're bound to have missed some stuff. If you have ideas for other categories and devices that might be good to include, let us know.

So what's included? Well we have a selection of connectors, including audio/video, all the USB types and some miscellaneous ones too. There's also a section on memory cards. We then have a range of commonly used microcontroller chips, before we get to the main meat of the book, which is all the different single board computers and dev boards out there.

As the name suggests, it's a pinout reference book that you can download for free. It's aimed at designers, engineers and tinkerers, and basically covers a good chunk of the regular components and boards people like us will come across while we're working on electronics projects.

Apache BookKeeper is a cluster of nodes called bookies. Each virtual file (a.k.a ledger) is divided into consecutive segments, and each segment is kept on 3 bookies by default (replicated by the client - i.e., the broker). Operators can add bookies rapidly since no data reshuffling (moving) between them is required. They immediately share the incoming write load.
