   ## Feature Request

   ### Is your feature request related to a problem?
   
   We have a shard table Account in 3 databases.
   
   There is a batch to loop the Account table to do a job.
   
   The Account table is so big . so we design a distributed batch running in 10 nodes.
   
   Each node reads a piece of data from a specific database for processing.
   
   A scheduler will assign each node which database to read from, from begin index to end index.
   
   So we need to specify a database when reading data, but we can still write data with ShardingAlgorithm as usual.
   
   ### Describe the feature you would like.
   make force route a one time thing , use the ShardingAlgorithm but value from hintmanager.
   
   or force route to a specify database .
   
   thanks
