基本功能

功能说明
Schema Migration

If the target schema does not exist, BladePipe will automatically generate and execute CREATE statements based on the source metadata and the mapping rule.

Full Data Migration

Migrate data by sequentially scanning data in tables and writing it in batches to the target database.

Incremental Data Sync

Sync of common DML like INSERT, UPDATE, DELETE is supported.
UPDATE and DELETE for tables without primary keys are not synced by default (manual selection required).

Table Name Mapping

Support the mapping rules, namely, keeping the name the same as that in Source, converting the text to lowercase, converting the text to uppercase, truncating the name by "_digit" suffix.

DDL Sync

Supports ALTER TABLE ADD COLUMN and DROP COLUMN.
