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.

Ten-year experience in DBMS testing
The history of SQL tests in Tarantool is fascinating. We used VDBE to adopt a part of SQLite code, namely the SQL query parser and the bytecode compiler. One of the main reasons was that SQLite code has almost 100% test coverage. However, the tests were written in TCL, and we don't use it at all. So we had to write a TCL-Lua convertor to port tests written in TCL, and imported them into the code base after optimizing the resulting code. We still use these tests and add new ones when necessary.

How a Single Line of Code Made a 24-Core Server Slower Than a Laptop
Not directly related, but https://github.com/nosqlbench/nosqlbench is very flexible benchmark tool for Cassandra and other distributed systems

Ten-year experience in DBMS testing
For performance testing, we also run common benchmarks: the popular YCSB (Yahoo! Cloud Serving Benchmark), NoSQLBench, LinkBench, SysBench, TPC-H, and TPC-C. We also run C Bench, our own Tarantool API benchmark. Its primitive operations are written in C, and scripts are described in Lua.

Requirements for running K8ssandra for development
We used NoSQLBench to perform moderate load benchmarks. It comes with a convenient Docker image that we could use straight away to run stress jobs in our k8s cluster.

Apache Cassandra 4.0: Taming Tail Latencies with Java 16 ZGC
Jonathan Shook created NoSQLBench to be a cross-platform performance testing tool that is easier to use than cassandra-stress and (much) more powerful than YCSB; in fact, its scripting layer is powerful enough to support things that no other testing tool can enable, with particular emphasis on modeling complex workloads with fidelity, as well as simulating realistic scenarios such as load spikes. As its name suggests, NoSQLBench is not Cassandra-specific and encourages participation from all who want to contribute; today there are clients for Cassandra, CockroachDB, JDBC, and MongoDB, as well as non-database products Kafka and Pulsar. If you’re serious about performance testing in 2021, you should check out NoSQLBench. You can get started at GitHub. Other useful links: releases, discord, docs.
