Release Date	Module	Feature	Release Details	Related Links
09-30	Data Replication	Data-Source Change Propagation	After a data source is modified, its configuration is updated in all unfinished data replication and comparison tasks. Before restarting a replication task, NineData checks whether the data source is reachable, then updates the task configuration and restarts it. Running or abnormal incremental replication tasks restart automatically. Bidirectional replication and distributed tasks are supported for updates and restarts.	Data Replication
09-30	Data Replication	Bidirectional Replication Loop Check	Before scheduling a bidirectional replication task, NineData checks loop-prevention conditions again, including whether the multi-active tags are valid and whether the required bidirectional replication conditions are met. If a check fails, the task exits with an error to prevent a replication loop.	Data Replication

09-09	Data Replication	Feature Optimization	The replication metadata-database connection pool now supports a configurable connection limit to improve stability in large clusters. Optimized the `hashCode` algorithm for `NULL` sharding-key values in DRDS bidirectional loop prevention. PostgreSQL full replication now retries automatically after a CSV write exception. Schema replication no longer fetches the current sequence value, improving replication performance. For table-batched writes with many `DELETE` operations and a single-column primary key, the writer uses a primary-key `IN` condition instead of multiple single-row `DELETE` statements. When some DML conditions are not matched during incremental batch writes, only the related unmatched DML is retried instead of the entire batch. An unmatched `DELETE` is not automatically compensated, except when an earlier `UPDATE` on the same row was also unmatched. MySQL incremental replication queries the log list less frequently to reduce its impact on server-side Binlog writes. SQL Server incremental replication disables the foreign key before writing when it encounters a foreign-key conflict.	Data Replication
09-09	Data Replication	BUGFIX	Fixed target constraint violations caused by trimming Oracle `CHAR`/`NCHAR` values; incremental parsing no longer applies `TRIM` to these types. Fixed Oracle `PreparedStatement` `WHERE` handling that applied `TRIM`, preventing index use and causing `CHAR` values without matching trailing spaces to fail to match. Fixed type-conversion issues where Oracle data remained `LONG DATA` after an online dictionary change. Fixed a replication interruption caused by an Oracle LOB online-column change that produced a `Dictionary Version Mismatch` parse error that could not be skipped. Fixed StarRocks write errors when records with the same primary key but different columns were merged without updating `RowMeta`. Fixed replication errors caused by updating row metadata without updating the corresponding record-block metadata during incremental batch row adjustments. Fixed handling of Oracle date default values. Fixed write failures when copying emoji or other special characters to MySQL without explicitly specifying a character set. Fixed parsing of Elasticsearch JSON and other object types.	Data Replication
09-09	Data Comparison	Oracle Full-Comparison Hash Fallback	Oracle full comparisons now use fallback SQL that calls `orahash` for each field when concatenated expressions are too long for the regular hash SQL.	Data Comparison
09-09	Data Comparison	Redis Stream Comparison Results	Fixed an issue where identical Redis Stream data was incorrectly reported as different.	Data Comparison
09-02	Data Replication	PostgreSQL-to-ClickHouse Incremental DDL	PostgreSQL-to-ClickHouse incremental replication now replicates DDL for added columns.	Data Replication
09-02	Data Replication	Doris Incremental Write Optimization	Optimized the StreamLoad write algorithm and performance for `* → Doris` incremental replication when only some fields are updated.	Data Replication

09-02	Database DevOps	OpenSearch Data Source	Added the OpenSearch data source with support for SQL Console, permission requests, approval processes, and related functions.	Create Data Sources SQL Console (RDBMS) Permission Application and Approval Manage SQL Approval Processes

06-24	Data Replication	Feature Optimization	When users click recheck during data replication prechecks, unsuccessful warning-level check items are rechecked to verify whether the user's changes have taken effect. Data replication tasks now support disabling subtasks such as schema replication, full replication, incremental log reading, and incremental data writing through parameters. Optimized response performance for data replication and data comparison request APIs. Optimized main-task and subtask runtime states for data replication to avoid cases where changed task states do not update task status and error information in the metadata database, affecting later operations. Optimized metadata read/write retry logic for data replication. When metadata writes encounter unique-key conflicts during exception retries, retries stop and feedback is returned quickly. Optimized data type conversion for OceanBase MySQL > Oracle schema replication.	Data Replication
06-24	Data Replication	BUGFIX	Fixed abnormal data type handling in OceanBase MySQL > Oracle schema replication.	Data Replication
06-17	Data Replication	New Features	Added OpenAPI interfaces for data comparison precheck, start, status query, result query, difference details, and correction SQL retrieval.	Data Compare OpenAPI

During MySQL bidirectional replication incremental log parsing, DML generated after the source writes to the target is filtered on the read side earlier, reducing log storage and computation.	Data Replication
06-17	Data Replication	BUGFIX	Fixed MySQL data source connection errors caused by GBase driver priority and MySQL driver loading. Fixed loss of field-related changes when SQL Server > MySQL incremental replication DDL involved tables with field mappings.

Data Replication
06-10	Data Replication	BUGFIX	Fixed an issue where objects could not be removed when modifying synchronized objects with only incremental replication selected and adding/removing objects at the same time. Fixed inaccurate target metadata in extreme concurrent data replication scenarios where DML metadata preparation did not wait for earlier DDL execution to finish.

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.
