dcp — the DCP capture SDK

Transport-layer data lineage for Python: DCP captures lineage inside the Postgres (psycopg 3) and Kafka (confluent-kafka) client libraries, where data physically moves, instead of from what applications report.

No code changes: run a script under dcp-instrument. On PyPI this package is named wiretap-dcp; the import name is dcp (the PyPI name dcp belongs to an unrelated project, so do not install both in one environment). On Linux or macOS (bash):

pip install "wiretap-dcp[postgres,kafka]"
DCP_EMIT=file://dcp_events.jsonl dcp-instrument python my_script.py

The event format, the benchmarks and the measured results are in the project repository: https://github.com/dev1702ed/Wiretap (start with its README, then docs/results/V1.md). Licensed under Apache 2.0.
