eBPF tools (2014-2019). On the Netflix Java/Linux/EC2 stack there were no working mixed-mode flame graphs, no production safe dynamic tracer, and no PMCs: All tools I used extensively for advanced performance analysis. Netflix has been the best job of my career so far, and I'll miss my colleagues and the culture. flame graphs (2014).

This occurs once data is safely stored within a local cache. To avoid this, it was announced at KubeCon 2019 in Barcelona that the OpenTracing and OpenCensus projects would converge into one project called OpenTelemetry and join the CNCF. These are core components and language-specific (such as Java, Python,Net, and so on).

Reads usually have apps waiting on them; writes may not (write-back caching). This is a 64-Gbyte memory system, and 48 Gbytes is in the page cache (the file system cache). Along with the numbers from the problem statement, this gives me a theory: Do the 100-Gbyte files bust the page cache, whereas 40-Gbyte files fit?

First and foremost, this allows you to implement arbitrarily complex caching behavior, but it has also been extended to let you tap into long-running background fetches, push notifications, and other functionality that requires code to run without an associated page.

Given the increasing importance of open source and the widespread use of HammerDB, the TPC adopted HammerDB in 2019 and now hosts the project on GitHub. Cached vs Scaled Workloads. A key difference between cached and scaled workloads is the implementation of keying and thinking time to introduce a pause of time between transactions.
