ivy_mooncake v1.0 beta1

Version Overview

[Release Date: June 30, 2026]

ivy_mooncake 1.0 beta1 is built on pg_mooncake 0.1.3 and adds support for IvorySQL's Oracle compatibility mode. For a comprehensive list of updates, please visit our documentation site

Like upstream, ivy_mooncake keeps a real-time columnstore mirror of your tables in Apache Iceberg, so you can run fast analytics on live OLTP data — powered by moonlink for streaming ingestion and pg_duckdb for query execution.

On top of that foundation, ivy_mooncake extends pg_mooncake to run natively on IvorySQL .

Features

• Adapted to the IvorySQL 5 kernel: Feature #1
  Completed adaptation for Oracle compatibility mode, — the CDC pipeline now understands IvorySQL's Oracle-mode types (NUMBER, VARCHAR2, Oracle DATE/TIMESTAMP, INTERVAL, BINARY_FLOAT/DOUBLE, RAW, XMLTYPE, …) and mirrors them into Iceberg.

• Enhanced Diagnostics & Lifecycle Management: Feature #2
  New diagnostics and lifecycle controls — mooncake.bgworker_status(), orphan-slot listing/cleanup, and automatic slot/publication teardown on DROP EXTENSION.

• Switchable dual-mode: Feature #2
  Flexibly control mode selection via a switch — choose between lightweight mode and high-performance mode.

• Containerized Deployment Support: Feature #3
  Supports one-click deployment of standalone or highly available IvorySQL 5.4 clusters via Docker Compose, docker images based IvorySQL 5.4.
