release "learningProcTest01", right click on "View Snapshot Agent Status", select "Start" in the popup window, you will find that the snapshot will only initialize one table instead of the entire three tables. After the command is completed, you will find that the table's subscription_status has changed to 2, as shown below As for the completion, both the ' immediate_sync ' and ' allow_anonymous ' properties are very simple and easy if you want to start. Just change the false to True, execute

In the context of replication, transactional publishing is the most widely used, and I have a scenario where there are basic and group two tables in the task database, and you need to provide some of the fields in the two tables to cache other programs, and the program needs to get the data in time. As a DBA you need to start with permissions and performance control, I use
Recently, I encountered a problem about the setting of commitbatchsize and commitbatchthreshold in SQL Server transactional replication. The explanation in the BOL is vague:
Commitbatchsize "is the number of transactions to be issued to the subscriber before a commit statement is issued. The default is 100 ."
in the SQL Server account of the Subscriber, giving the distributor permission to push the data to the Subscriber.6. Set add New item do not initialize entire snapshotThe publisher often creates new tables or other database objects, such as stored procedures or functions, that you need to initialize if you want to add these new items to an existing subscription. But the default setting is to initialize all

Another unique feature of transactional replication is the support for parallel snapshot processing, which is also a new feature of SQL Server 2000
