Andreas Andreakis , Ioannis Papapanagiotou Overview Change-Data-Capture (CDC) allows capturing committed changes from a database in real-time and propagating those changes to downstream consumers [1][2]. There are several open source CDC projects, often using the same underlying libraries, database APIs, and protocols.

OpenTelemetry , the open source observability tool, has become the go-to standard for instrumenting custom applications to collect observability telemetry data. However, this method limited us to instrumenting the code manually and collecting specific sets of data we defined upfront. What is OneAgent?

Stretched tools used outside of their key use-cases and beyond their core capabilities result in unreliable data leading to wrong decisions or a misplaced sense of safety. Lots of data intended to help and aid, but instead results in too much noise and unnecessary alerts due to the lack of intelligent root-cause analysis and transparency.

For example, you could reduce compression efficiency , because that works better with more data. Server push allows a server to send response data without first waiting for a request from the client. As such, a micro-optimization is, again, how you probably need to fine-tune things on a low level to really benefit from it.
