数据链路

基本功能

功能	说明
Full Data Migration	Migrate data by sequentially scanning data in tables and writing it in batches to the message 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.

高级功能

功能	说明
消息格式	支持以下消息格式，文档：消息格式说明 CloudCanal内置格式 AlibabaCanal兼容格式
Topic Mapping Rules	By default, Topic is formed by connecting source instance id, database, and table with . in between. 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.
Setting Target Primary Key	Change the primary key to another field.

源端数据源

前置条件

条件	说明
账号权限	需要权限如下(以自建数据库为例): GRANT ALL PRIVILEGES ON DATABASE 同步库 TO 同步账号（或同步库 information_schema 中所有视图的 SELECT 权限和需要同步表、索引、约束的 SELECT 权限) ALTER USER 同步账号 REPLICATION
增量同步准备	准备动作按如下步骤进行: 修改 postgresql.conf, 设置 wal_level=logical 和 wal_log_hints = on 修改 pg_hba.conf, 设置 host replication 同步账号 CIDR网段 md5 , host 同步库 同步账号 CIDR网段 md5, host postgres 同步账号 CIDR网段 md5 重启 PostgreSQL
网络准备	迁移同步节点（sidecar）可连接 PostgreSQL 标准交互接口（如 5432）

任务参数

参数名称	说明
fullFetchSize	全量扫描数据设置的 fetch size
eventStoreSize	缓存解析完毕的增量事件缓存大小
ignoreGisSRID	解析 GIS 数据类型时是否忽略 SRID
defaultGisSRID	设置 GIS 数据类型的 SRID
