groupSourceTablesByRouteRule

public List<Set<org.apache.flink.cdc.common.event.TableId>> groupSourceTablesByRouteRule(Set<org.apache.flink.cdc.common.event.TableId> tableIdSet)

Group the source tables that conform to the same routing rule together. The total number of groups is less than or equal to the number of routing rules. For the source tables within each group, their table structures will be merged to obtain the widest table structure in that group. The structures of all tables within the group will be expanded to this widest table structure.

参数:

tableIdSet - The tables need to be grouped by the router

返回:

The tables grouped by the router
