Apache JMeter
Apache JMeter open-source load testing tool for analyzing and measuring the performance of a variety of services
JMeter is a well-known tool for load or stress testing, it basically sends requests to your application within the given time, according to the behaviour plan you provided. The plans are designed to be detailedly configurable and focused on load-testing jargon. That makes the JMeter a comprehensive solution, however makes it a bit hard to understand & focus on the well written tests.

Apache Log4j 2
Apache Log4j 2 is an upgrade to Log4j that provides significant improvements over its predecessor, Log4j 1.x, and provides many of the improvements available in Logback while fixing some inherent problems in Logback's architecture.
> When it was first revealed in early December 2021, the Log4Shell bug was described as one of the most severe security vulnerabilities ever.
> The Apache Software Foundation, which maintains the open-source tool, quickly released a patch...
Apache horribly mismanaged this and did not release a patch until it was already widely known and being exploited in the wild. They also messed up and had to release several subsequent patches to actually fix the vulnerability.
Remember: this vulnerability was disclosed to them in November.

Project mention: Need help navigating the Java ecosystem (coming from C++) | reddit.com/r/ExperiencedDevs | 2023-01-07
Martin Thompson is one of the leaders in that space: his blog is a really great place to start. His Agrona library is a bunch of high-performance data structures, which you can use directly, but which can also serve as examples of writing such code.

hypersistence-utils
The Hypersistence Utils library (previously known as Hibernate Types) gives you Spring and Hibernate utilities that can help you get the most out of your data access layer.
Unfortunately, you cannot smoothly wrap the sequence-based IDs with value objects. There are solutions, but they are rather cumbersome. I left the proposal to the Hibernate types project of adding support to this feature. You’ve already seen the benefits of user-defined types. So, you can rate up my issue to make it more popular.

Project mention: Minehut Server TPS Is Low Even After Upgrading The Server Specs | reddit.com/r/admincraft | 2023-01-24
You should use Spark (https://spark.lucko.me/) to gather some information about what's actually "taking up time" in the ticks.

Automon
Automon combines the power of AOP (AspectJ) with monitoring or logging tools you already use to declaratively monitor your Java code, the JDK, and 3rd party libraries.

Project mention: FileOutputStream v. ByteArrayOutputStream: is there a noticeable difference in memory usage? | reddit.com/r/javahelp | 2022-12-20
I'm using fastexcel to create the excel file, and I'm flushing it to the OutputStream after every row is written. Right now, I am using a FileOutputStream to write to disk. When the excel file is done being generated, I read it back in using InputStreamResource and stream the response. My thought process is that a ByteArrayOutputStream keeps everything in memory even if I'm flushing the excel file after every row, so I used the FileOutputStream. Does my logic track here? Or am I unnecessarily slowing things down with expensive filesystem IO?

parallel-consumer
Parallel Apache Kafka client wrapper with per message ACK, client side queueing, a simpler consumer/producer API with key concurrency and extendable non-blocking IO processing.
Hi everyone, my name is Daniel and I run a website called Rock the JVM [1]. It's a popular site and blog for Scala, and we've recently started to create guides and materials for other libraries and languages. This video is about - maximizing producer throughput - minimizing producer latency - running multiple consumers vs number of partitions, analyzing parallelism - parallel consumers [2] for 1000x perf increase vs 1x single-threaded consumer I also have written forms of all videos as long-form blog posts, and you can find the written guide here [3]. I hope you like it - let me know if you need anything or have any questions!
