Trace Context already has many implementations. One of them is OpenTelemetry.
As in Python, it creates spans for every method call and HTTP entry point. It also instruments JDBC calls, but we have a Reactive stack and thus use R2DBC. For the record, a GitHub issue is open for adding support.
While Trace Context is a W3C specification and OpenTelemetry is a de facto standard, many solutions exist to collect, store and display traces on the market. Each solution may provide all three capabilities or only part of them. For example, the Elastic stack handles storage and display, but you must rely on something else for collection. On the other hand, Jaeger and Zipkin do provide a complete suite to fulfill all three capabilities.
