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.

Is anyone using PyPy for real work?
I'm maintaining an internal change-data-capture application that uses a python library to decode mysql binlog and store the change records as json in the data lake (like Debezium). For our most busiest databases a single Cpython process couldn't process the amount of incoming changes in real time (thousands of events per second). It's not something that can be easily parallelized, as the bulk of the work is happening in the binlog decoding library (https://github.com/julien-duponchelle/python-mysql-replicati...).
So we've made it configurable to run some instances with Pypy - which was able to work through the data in realtime, i.e. without generating a lag in the data stream. The downside of using pypy was increased memory usage (4-8x) - which isn't really a problem. An actually problem that I didn't really track down was that the test suite (running pytest) was taking 2-3 times longer with Pypy than with CPython.
A few months ago I upgraded the system to run with CPython 3.11 and the performance improvements of 10-20% that come with that version now actually allowed us to drop Pypy and only run CPython. Which is more convenient and makes the deployment and configuration less complex.

Why Binlog size grows drastically when isolation level set to "Repeatable Read" & When isolation level set to "Read Committed" the size of Binlog file reduces ?

How to Use BinLogs to Make an Aurora MySQL Event Stream
The BinLogStreamReader has several inputs that we need to retrieve. First we'll retrieve the cluster's secret with the database host/username/password and then we'll fetch the serverId we stored in S3.

How is everyone ingesting backend relational data?
From backend relational tables to data warehouses my team has mostly relied on change data capture replication. We use MySQL upstream, and historically used AWS DMS or Attunity Replicate to replicate directly to SQL server. Recently we made the switch to Snowflake, and used mostly AWS DMS to replicate CDC data to S3 (lists individual inserts, updates, deletes), and then from there use snowpipes to copy to snowflake and then a job to merge that data into the target table to get the latest state. In addition we've used this library in production https://github.com/noplay/python-mysql-replication, and still use it today for one high volume, critical data source. Generally we see data go end to end in a matter of minutes, but occasionally there are spikes in latency.

Does anyone prefer the CLI over the shell, or other way around? If so, why?
Also, check out MyCLI. https://github.com/dbcli/mycli "Terminal Client for MySQL with AutoCompletion and Syntax Highlighting"

Is there any terminal based database manager?
Hello! So far I have seen tools like mycli or gobang, but I was wondering if there were more tools for database management from the terminal? Either for relational or non-relational databases.

The Dedicated Maintainers Behind Lesser-Known Open Source Projects
However, there are many open source projects that are widely used but not well-known, including cURL, ImageMagick, MyCLI, Homebrew, Apache Log4j, and OpenSSL. This article will take a closer look at these unsung heroes of the open source world. I do not want to give them a business model or financial advice in this article. This largely depends on the author's personal experience and values. I just want to raise more awareness about these open source projects.
