Release Date	Module	Feature	Release Details	Related Link
04-29	Data Replication	Feature Optimization	Optimized the data replication task creation process. Creating a new replication task now requires purchase before startup. Optimized Redis full replication performance. Optimized structure replication from varchar in MySQL-compatible databases to DB2 types. Optimized the replication logic for the blob type in openGauss.	None
04-29	Data Replication	Bug Fix	Fixed an issue where field information in MySQL data replication was not sorted by ORDINAL_POSITION.

04-22	Database DevOps	SQL Console	Optimized support for PostgreSQL-like data sources in SQL Intelligent Optimization.	SQL Console (RDBMS)
04-22	Data Replication	Feature Optimization	Optimized the precheck logic for data replication: for data existence checks within a specified time range, NineData now prioritizes select 1 from table limit 1 and falls back to information_schema queries after timeout, so that real data existence can still be determined as much as possible when metadata is inaccurate. Optimized the loop detection logic in data replication prechecks. GaussDB incremental replication now supports DDL replication for non-table objects such as procedures, functions, and sequences. PostgreSQL incremental replication now supports parsing and replication of COMMENT ON CONSTRAINT syntax. Optimized foreign key dependency handling in PostgreSQL structure replication.	None

04-08	Data Replication	Feature Optimization	Enhanced object configuration conflict detection in data replication prechecks, enabling identification of loop configurations in unfinished replication tasks and cases where multiple tasks replicate the same table. Optimized the startup mechanism for bidirectional replication tasks. Starting the forward task no longer depends on the reverse task having already started, avoiding failures where the forward task could not start because the reverse task was not started.	None
04-01	Database DevOps	SQL Task	Optimized the backup capability of Oracle SQL tasks.	SQL Tasks
04-01	Data Replication	New Features	PolarDB-X distributed databases now support multi-stream CDC reads and replication. Optimized distributed data source support: distributed task splitting is supported; parent tasks wait until all subtasks in stages such as schema, full, and incremental replication finish before moving to the next stage; subtasks wait until the parent task's previous stage is finished before starting. For bidirectional replication, reverse replication tasks now wait until the forward task finishes full replication before collecting logs for the reverse incremental replication task.	Data Replication
04-01	Data Replication	Redis / PolarDB-X Replication Optimization	Optimized the Redis full replication write mechanism. Some data objects are converted from Restore objects to RdbCommand and written through pipeline uniformly, reducing performance degradation when restore and send calls alternate. Optimized PolarDB-X centralized incremental replication batch write performance.	Data Replication
