Upstream Creators

pg_mooncake, duckdb_mooncake, and moonlink were created by Mooncake Labs. All core architectural credit — including the hybrid rowstore + columnstore design, the Moonlink real-time Iceberg buffer engine, logical replication WAL ingestion, and the DuckDB execution bridge — belongs to the original Mooncake Labs authors and contributors.

Repository Lineage

Documentation Provenance & Recovery

The original upstream documentation website (https://docs.mooncake.dev/) was taken offline after the upstream project transitioned direction, and no public documentation source repository remained available on GitHub.

To preserve the reference manuals for both v0.2 (Moonlink + Iceberg) and v0.1 (Delta Lake):

1. Wayback Machine Snapshot Extraction: All 34 canonical documentation pages (17 v0.2 pages, 16 v0.1 pages, and 1 Moonlink overview page) plus 30 historical alias routes and 4 original architecture diagrams were recovered from the Internet Archive Wayback Machine snapshot (2025-12-07).
2. Verification Against v0.3.0 Source: Every SQL function signature, configuration GUC, environment variable, and error code was cross-checked against the pgsty/pg_mooncake v0.3.0 source tree (pgrx 0.19.3, pg_duckdb 1.2.0, duckdb_mooncake v0.0.2, moonlink v0.0.1).
3. Bilingual Translation & Engineering Reports: PGSTY added full Simplified Chinese translations (/zh/docs/) and published engineering reports covering the DuckDB 2.0 adaptation, pgrx 0.19.3 migration, and the 2026-11-05 RustSec dependency audit.

Every page adapted from the historical upstream documentation includes upstream_source and upstream_link metadata in its front matter.
