Export Data or Table Structure with MYSQLDUMP

Export Data or Table Structure with MYSQLDUMP

Doris has supported exporting data or table structures through the mysqldump tool after version 0.15

Examples​

Export​

  1. Export the table1 table in the test database: mysqldump -h127.0.0.1 -P9030 -uroot --no-tablespaces --databases test --tables table1
  2. Export the table1 table structure in the test database: mysqldump -h127.0.0.1 -P9030 -uroot --no-tablespaces --databases test --tables table1 --no-data
  3. Export all tables in the test1, test2 database: mysqldump -h127.0.0.1 -P9030 -uroot --no-tablespaces --databases test1 test2
  4. Export all databases and tables mysqldump -h127.0.0.1 -P9030 -uroot --no-tablespaces --all-databases For more usage parameters, please refer to the manual of mysqldump

Import​

The results exported by mysqldump can be redirected to a file, which can then be imported into Doris through the source command source filename.sql

Notice​

  1. Since there is no concept of tablespace in mysql in Doris, add the --no-tablespaces parameter when using mysqldump
  2. Using mysqldump to export data and table structure is only used for development and testing or when the amount of data is small. Do not use it in a production environment with a large amount of data.
