Export Data from TiDB

This page describes how to export data from your cluster in TiDB Cloud.

TiDB does not lock in your data. Sometimes you still want to be able to migrate data from TiDB to other data platforms. Because TiDB is highly compatible with MySQL, any export tool suitable for MySQL can also be used for TiDB.

You can use the tool Dumpling for data export.

Download and install TiUP:

curl --proto '=https' --tlsv1.2 -sSf https://tiup-mirrors.pingcap.com/install.sh | sh

Declare the global environment variable:
Note
After the installation, TiUP displays the absolute path of the corresponding profile file. You need to modify .bash_profile in following command to the path of your profile file.
```
source .bash_profile
```
Install Dumpling.
```
tiup install dumpling
```
Export your data using Dumpling from TiDB.
```
tiup dumpling -h ${tidb-endpoint} -P 3306 -u ${user} -F 67108864 -t 4 -o /path/to/export/dir
```
If you want to export only the specified databases, use -B to specify a comma separated list of database names.
The minimum permissions required are as follows:
- SELECT
- RELOAD
- LOCK TABLES
- REPLICATION CLIENT
Currently, Dumpling only supports the Mydumper format output, which can be easily restored into MySQL compatible databases by using TiDB Lightning.
