MySQL 到 Amazon MSK
| 功能 | 说明 |
|---|---|
Schema Migration | If the specified Topic after mapping does not exist in the Target, BladePipe will automatically create the Topic, allowing setting the number of partitions. |
Full Data Migration | Migrate data by sequentially scanning data in tables and writing it in batches to the message-oriented middleware. |
Incremental Data Sync | Sync of common DML like INSERT, UPDATE, DELETE is supported. |
Subscription Modification | Add, delete, or modify the subscribed tables with support for historical data migration. For more information, see Modify Subscription. |
Position Resetting | Reset positions by file position or timestamp. Allow re-consumption of incremental data logs in a past period or since a specific Binlog file and position. |
Metadata Retrieval | Retrieve the target metadata with filtering conditions or target primary keys set from the source table. |

Topic Mapping Rules | By default, Topic is formed by connecting source instance id, database, and table with . in between (e.g., my-vgpq6q097174t6t.dingtax.app_key). Also, it supports the mapping rules, namely, keeping the name the same as that in Source, converting the text to lowercase, converting the text to uppercase. |
Table-level Topic | Create Topics corresponding to the tables in the Source, and the table partitions can be obtained automatically. |
DDL Dedicated Topic | Allow specifying a Topic for DDL. If not specified, DDL time is placed in partition 0 of the Topic created from the corresponding table. |
Scheduled Full Data Migration | For more information, see Create Scheduled Full Data DataJob. |
Custom Code | For more information, see Custom Code Processing, Debug Custom Code and Logging in Custom Code. |
Data Filtering Conditions | Support data filtering using WHERE conditions, with SQL-92 as the SQL language. For more information, see Data Filtering. |
