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.

Your Thoughts on OLAPs Clickhouse vs Apache Druid vs Starrocks in 2023/2024
DevRel for StarRocks. Trino doesn't have a great caching layer (https://github.com/trinodb/trino/pull/16375) and performance (https://github.com/trinodb/trino/issues/14237) and https://github.com/oap-project/Gluten-Trino. In benchmarks and community user testing, StarRocks has outperformed.

Making Hard Things Easy
What if my SQL engine is Presto, Trino [1], or a similar query engine? If it's federating multiple source databases we peel the SQL back and get... SQL? Or you peel the SQL back and get... S3 + Mongo + Hadoop? Junior analysts would work at 1/10th the speed if they had to use those raw.

Questions about Athena, Trino and Iceberg
The good thing is that the concepts in terms to the SQL supported by Trino transfers between them all. So its completely reasonable to start with one and move to another. In fact that is something that happens regularly. I invite to you check out the talks from the Trino Fest event that is just wrapping up today. There are presentations about all these aspects and different scenarios users encounter. All videos and slides will go live on the Trino website soon. Also feel free to join the Trino slack to chat about about all this with other users.

Uber Interview Experience/Asking Suggestions
One place to look are the projects repo's and docs, once you have a good idea of how the system is architected poking around pieces of the codebase can be helpful in letting you really understand their internals. I personally enjoy going through spark repo and trino repo and the documentation for both projects is decent and can answer many of your questions.

What is the separation of storage and compute in data platforms and why does it matter?
However, once your data reaches a certain size or you reach the limits of vertical scaling, it may be necessary to distribute your queries across a cluster, or scale horizontally. This is where distributed query engines like Trino and Spark come in. Distributed query engines make use of a coordinator to plan the query and multiple worker nodes to execute them in parallel.

Multi-Database Support in DuckDB
We have some of this functionality in Presto (https://github.com/prestodb/presto), but it takes fair bit of work to implement it for all the different backends.

Rust std:fs slower than Python
Note that glibc has a similar problem in multithreaded contexts. It strands unused memory in thread-local pools, which grows your memory usage over time like a memory leak. We got lower memory usage that didn't grow over time by switching to jemalloc.
Example of this: https://github.com/prestodb/presto/issues/8993

Ask HN: What are some SQL transpilers?
SQLGlot is a really awesome tool that can. transpile SQL to various dialects -- https://news.ycombinator.com/item?id=31981568. What are some other SQL transpilers? I believe Presto (https://github.com/prestodb/presto) includes one, but what are others?

Memoization in Cost-based Optimizers
You may find a similar design in many production-grade heuristic optimizers. In our previous blog post about Presto, we discussed the Memo class that manages such references. In Apache Calcite, the heuristic optimizer HepPlanner models node references through the class HepRelVertex.
