Absrtact: Background Data Migration is a very common scene in the database operation dimension. Data migration is divided into total and incremental. In order to pursue speed, we usually use concurrent methods to migrate the data in a full volume. When you export data in a full volume, you typically choose to record-level concurrency, so it's often about the process of splitting (partitioning) of a table (s

Background introduction With the development of business and the change of demand, we pursue the use of different types of databases and give full play to their respective characteristics. If you decide to adopt a new type of database, you need to migrate the existing data to the new database. In this type of requirement, it is particularly important to import data from SQL Server into MongoDB. In the face of this demand, we first think of Baidu to f

MySQL Library has a table, the amount of data around 1 billion, basically for this table operation is meaningless, so want to test the migration to MongoDB shared architecture will be improved. So whined whined built a 3 shard MONGO environment, and the MySQL in this large table data exported to CSV format, and finally use the Mongoimport tool to successfully import more than 1 billion of the data into the

Scenario: in the production environment, all machines are replaced. It takes a short time to affect or suspend the service (the time for configservers migration) Step: migrate three configservers. We recommend that you do not change the host name for migration. The old mongos can still be accessed during and after migration, for more information, see MigrateConfi

Migrate data from an existing MongoDB replica set to a new shard cluster and design three migration scenarios. Scenario One: Synchronize the data first, then set up the Shard cluster, and finally configure the Shard cluster. export the data that needs to be migrated, set up the first replica set, import the data into the replica set, add two additional replica sets, start config server, start MONGOs serv

Preface The migration technology of virtual machines provides a simple method for server virtualization. Currently, popular virtualization products VMWare, xen, hyper-V, and KVM all provide their own migration tools. Among them, the Linux platform's open-source virtualization tool KVM has developed rapidly, and the migration features of KVM-based virtual machines
