NineData Community Edition Release Note

Official Github

Version: 4.4.0 (Official Release on 2025.08.13)

Module	Feature	Release Details
Product Features	Database DevOps	New Features Database Version Management: Added database version management. For MySQL databases with version management enabled, the system automatically collects DDL changes for the database and saves them as a version. Change scripts and rollback scripts can be generated between different versions. Stored Procedure Debugging (Oracle): Added support in the SQL Console for compiling and debugging stored procedures, functions, and package objects in Oracle databases. For objects with compilation errors, detailed error information is provided. Supports setting breakpoints, step-by-step execution, and procedure-by-procedure debugging. Data Export (MongoDB): Added support for exporting MongoDB data. JSON files can be exported via SQL statements. MySQL Lock Wait Management: Added SQL execution lock wait configuration rules, allowing you to set lock wait timeouts and retry counts to avoid lock contention caused by task changes, ensuring database change safety. OpenAPI Extensions: Added 11 new OpenAPI endpoints, covering account management, user management, role management, operation auditing, and data source permissions. Enhancements OnlineDDL Non-locking Changes: Added lock wait timeout and retry management for the instant algorithm in OnlineDDL non-locking table structure changes. During changes, you can now view replayed incremental log counts, replay delays, binlog positions, and response delays.
Product Features	Data Replication & Comparison	New Features PostgreSQL > StarRocks: Supports schema replication, full replication, and incremental replication; supports full/fast/periodic/inconsistency recheck comparisons. OpenGauss Oracle Homogeneous Replication: Supports schema replication, full replication, and incremental replication; supports full/fast/periodic/inconsistency recheck comparisons. OpenGauss PostgreSQL Homogeneous Replication: Supports schema replication, full replication, and incremental replication; supports full/fast/periodic/inconsistency recheck comparisons. OpenGauss MySQL Homogeneous Replication: Supports schema replication, full replication, and incremental replication; supports full/fast/periodic/inconsistency recheck comparisons. Enhancements Optimized MySQL high-performance synchronization by improving foreign key dependency parsing, preventing write failures caused by different foreign key write orders. PostgreSQL incremental replication now supports syncing CREATE TABLE LIKE DDL, and allows specifying which DDL types to replicate. MySQL data replication now supports the latin1 character set. PostgreSQL incremental replication improved support for copying data from the postgis plugin. Enhanced object name handling in schema replication tasks, including converting names to uppercase or lowercase.
Product Features	Basic Services	New Features Task Management: Added an Operations Center providing task management capabilities, allowing you to view task lists, scheduling logs, and other detailed information. Enhancements Fixed metadata database initialization timeout issues.
