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.

Substrait: Cross-Language Serialization for Relational Algebra
4. The workers (if distributed) or the engine (if single-box) executing the execution plan, by performing the actual computations on actual bytes.
(Note that this is a cartoon version and any given engine will have differences, eg Presto/Trino does not have a clear distinction between LP and Physical Plan.)
1) and 4) are broadly similar across engines, while 2) and 3) vary widely partially because of different requirements (reliability, latency, etc). Projects such as Apache Arrow and Velox (https://github.com/facebookincubator/velox) are making common tools for 4), and as mentioned ANSI SQL, ZetaSQL, Calcite, and Substrait are making common tools for 1).
