Can shardingsphere be used to implement mixed data association query after database division?
Example: Database 1: tables A1, B1 Database 2: tables A2, B2 How to associate A1 with B2 query? "Routing to multiple data nodes supports paging, de duplication, sorting, grouping, aggregation and association query (cross database association is not supported)." What does it mean that it is not clear (cross Library Association is not supported)? Test: Configure sharding: Database 1: table A1 Database 2: table B2 The query results of table A1 and table B2 are both normal. When table A1 is used as the main table to associate table B2, an error is reported: table B2 cannot be found in database 1
