Welcome to the SPQR wiki! You will find an in-depth project documentation accompanied by a set of tutorials revealing the ease of using SPQR in real-time streaming context.

The first version of SPQR ("spooker") was released under the acronym ASAP. Due to trademark issues it was later changed. From a technical perspective changing the name came along with some simplifications when it comes to pipeline setup. A number of generalization attempts were removed to simplify and speed up the use of SPQR in different context.

For example, the mailbox is not a pipeline component anymore that may be replaced by customized implementation on the fly but now uses the only available implementation based on chronicles. Although it restricts flexibility it reduces complexity and leads to faster deployment processes.

As an introduction to SPQR we recommend reading about the event processing paradigm that the framework follows: pipelines. You will learn about micro pipelines, macro pipelines, data sources, operators and emitters.

If you want to start immediately, the build and deployment instructions will guide you the way ;-)
