Applicable scenarios of TiDB tools

Based on the applicable scenarios of data migration tools, this document introduces the selection of migration tools in some common scenarios.

Deploy operation and maintenance TiDB on physical machine or virtual machine

When you need to deploy and maintain TiDB on physical or virtual machines, you can first install TiUP, and then manage many components of TiDB through TiUP, such as TiDB, PD, TiKV, etc.

Deploy operation and maintenance TiDB on Kubernetes

When you need to deploy and maintain TiDB on Kubernetes, you can first create a Kubernetes cluster and deploy TiDB Operator, and then use TiDB Operator to deploy and maintain the TiDB cluster.

import data from CSV to TiDB

When you need to import compatible CSV files exported by other tools into TiDB, you can use TiDB Lightning.

Import full data from MySQL/Aurora

When you need to import full data from MySQL/Aurora, you can use Dumpling Export data as SQL dump files, then use TiDB Lightning Import data into the TiDB cluster.

Migrate data from MySQL/Aurora

When you need to import full data from MySQL/Aurora and migrate incremental data, you can use TiDB Data Migration (DM) complete Migrate data from Amazon Aurora to TiDB.

If the full amount of data is large (TB level), you can use Dumpling Complete the migration of full data with TiDB Lightning, and then use DM to complete the incremental data migration.

TiDB cluster backup and recovery

When a TiDB cluster needs to be backed up or restored later, you can use BR.

In addition, BR can also perform Incremental backups and Incremental Recovery.

Migrate data to TiDB

When you need to migrate data from a TiDB cluster to another TiDB cluster, you can use Dumpling Export full data from TiDB as SQL dump files, then use TiDB Lightning Import data to TiDB.

If you also need to perform incremental data migration, you can use TiDB Binlog.

TiDB incremental data subscription

When you need to subscribe to changes in TiDB incremental data, you can use TiDB Binlog.
