 # Batch Jobs
 
-For synchronization of database information from data source. 
-The behavior differs greatly depending on whether you use SynchronizeDataSources or not. 
-All batches except SynchronizeDataSources are new beta batches added to improve batch operations.
-
-## SynchronizeDataSources
-
-Synchronize all data from all data sources. 
-IgnoredTables and MskedData will work. 
-If the number of schemas and tables to be synchronized is large, it will take a long time to synchronize. 
-Until v0.8.1, the target schema was dependent on the search_path in PostgreSQL and Redshift. Starting from the next version, search_path will no longer be used. Synchronize all visible schemas by a user account of Dmemo access.
-
-
-## Import Batches
-
-This is a new batch that replaces SynchronizeDataSources. New batches have been created to reduce the time spent on fetching and to make it easier to manage the schemas to be fetched. 
-**This is a beta version and is currently in trial.** 
-IgnoredTables and MskedData work. Only schemas that have SchemaMemo and are linked in Dmemo will be imported. 
-If you don't want to include them, the Dmemo administrator can edit the DataSource and unlink it. 
-Since we have created batches for each granularity, we need to specify the target with an argument for each granularity. 
-
-### For Examples
-```
-$bundle exec rails runner 'ImportDataSourceDefinitions.run("DWH”)’
-
-$bundle exec rails runner 'ImportTableDefinitions.run("DWH", “sample_schema", “target_table”)'
+Schemas, tables, and columns can be imported using `ImportDataSourceDefinition` job. Please run the job periodically.
+Note that only linked schemas are imported by the job. The settings can be configured by admins.
+
+```console
+$ bundle exec rails runner 'ImportDataSourceDefinitions.run("DWH”)'
+$ # If you want to import just a specific table:
+$ bundle exec rails runner 'ImportTableDefinitions.run("DWH", “sample_schema", “target_table”)'
+$ # Or if you want to import all schemas:
+$ bundle exec rails runner 'SynchronizeDefinitions.run'
 ```
-
-## SynchronizeDefinitions
-
-Run `ImportDataSourceDefinitions` for all data sources.
