Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

FoundationDB: A Distributed Key-Value Store
When I was writing a Haskell client library for Hyperdex, another distributed kv store, I found it incredibly helpful to implement a simulator for correctness. This helped me identify which behavior was unspecified (arithmetic overflow: should error) or where my simulator deviated.

Alas, I think Hyperdex development paused a few years later. It's a shame that it stopped then.

FoundationDB: A Distributed Key-Value Store
I've been tooling around with "Tuple Database", which claims to be FoundationDB for the frontend (by the original dev of Notion).
https://github.com/ccorcos/tuple-database/
I have found it conceptually similar to Relic or Datascript, but with strong preformance guarantees - something Relic considers a potential issue. It also solves the problem of using reactive queries to trigger things like popups and fullscreen requests, which must be run in the same event loop as user input.

Use of Posh for frontend development?
As an alternative to datascript you might be interested to try https://github.com/wotbrew/relic which does materialized views of queries with incremental maintenance.

Out of the Tar Pit (2006) [pdf]
I came across this after seeing relic[0] submitted the other day and thought it was pretty interesting.
I've been into CRDTs for a while and have started wondering about generic mechanisms for distributed data. This lead me to read a lot more about the Relational Model of data and eventually to the Event Calculus.
What's interesting to me is that these things end up feeling a lot like CRDTs[1] or Event Sourcing. I haven't quite finished pulling on these threads but the relic link was a timely read considering!
I really liked the first half of this paper and the Authors categorization of complexity. However the second half fell a bit short for me. It seems they made the same mistake as many other people (SQL != Relational) and their idea of Feeders and Observers seems a bit more like an escape hatch than an elegant method for interfacing with the outside would.
