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.

Doxa - a simple db that copies the functionality of datascript, using meander as a query tool
You might be able to use my library: https://github.com/wotbrew/idx. Would add a tiny cost for the pulls but you should be able to beat data-script on many queries (by using hash indexes directly to entry vs btree indexes to eid).

Why Doesn't Postgres Use My Index
To test various indexes, we don’t need to create them. We can use HypoPG extension that can analyze the index without creating it in the database.

Show HN: PostgreSQL Index Advisor
It works particularly well with pg_stat_statements[0] which tracks execution statistics of all SQL statements executed on your Postgres database.
It leans heavily on HypoPG[1], an excellent extension to determine if PostgreSQL will use a given index without spending resources to create them.

YugabyteDB hypopg: hypothetical indexes
This is an introduction to the hypopg PostgreSQL extension for YugabyteDB 2.15.3.0. Hypopg allows the creation of hypothetical indexes, so indexes that do not really exist. This means this allows you to see what an index would do if it were created, without it actually being created, and therefore not influencing anything on the database. YugabyteDB 2.15.3.0 is a preview version of the YugabyteDB database.

Why Can't Database Tables Index Themselves?
There's a lot of good ecosystem stuff around this:
https://github.com/HypoPG/hypopg
HypoPG is a PostgreSQL extension adding support for hypothetical indexes.
An hypothetical -- or virtual -- index is an index that doesn't really exists, and thus doesn't cost CPU, disk or any resource to create. They're useful to know if specific indexes can increase performance for problematic queries, since you can know if PostgreSQL will use these indexes or not without having to spend resources to create them.
