PoC of Ardoq based on Rama - Ardoq hackaton 2023.

See doc/ for detail.

Note that Rama AOT compiles a specific Clojure version in its jar, so you can't specify a different version of Clojure in your dependencies.

• Awesome
• Some macros lack docstring, e.g. <<sources, source>
• Currently, Rama has Clojure 1.11.1 built-in but Cursive believes random-uuid doesn't exist (though it works fine in the repl)

• Run with lein profiles dev,provided
• Had to add nrepl dependency to for Cursive

• See my #rama questions https://clojurians.slack.com/archives/C05N2M7R6DB/p1702471642548209
• Topologies: finish with local-transform to write the data
• I can't use Clojure flow control constructs such as or in a dataflow > use or>, <<if etc. Q: What can I use??
  • println
• Q: How to do compare-and-set ? Use assert! in the flow?
• How to throw an exception? A: assert! or throw! ? DON'T: "Any exception thrown anywhere in the processing of a depot record will cause that topology event to retry processing of that record"
• Tip: Use rama-helper's idgen (module-local ID sequence) for 64b IDs + a pstate mapping it to uuids - a long 1/2 the size of uuid
• Can't throw / assert in a flow - keeps retrying
• Implementing CAS
