Designing the Telemetry Capture System

Design a per-thread buffer architecture to eliminate write-side contention.

Implement a manager class to hold a collection of SPSC ring buffers, one for each instrumented thread.

Implement a background consumer thread that polls all thread buffers and consolidates events.

Explain the role of C++ preprocessor macros for code instrumentation.

Implement a variadic macro that captures source location, timestamp, and a formatted message.

Use preprocessor directives to make the capture macro a no-op when a profiling flag is disabled.

Implement a string interning table using a hash map to reduce data size and enable fast comparisons.

Serialize event data into a compact binary format before pushing to the ring buffer.
