If you’re familar with MongoDB and its schemaless document structure, RethinkDB works in a similar manner with flexible schemas. With RethinkDB, you can write a client in any language (Python, JS, Ruby etc…) to listen to specific database queries and perform operations when there’s a change in the database. https://dchua.com/posts/2014-08-28-mysql-backup-process/ Thu, 28 Aug 2014 00:00:00 +0000 https://dchua.com/posts/2014-08-28-mysql-backup-process/ How I usually prepare the backup regime of my mysql/mariadb databases of all my newly provisioned servers is to do the following tasks: Create a DBA user > create user 'dba'@'localhost'; Give the DBA user only the relevant access just for backing > GRANT SELECT, SHOW VIEW, RELOAD, REPLICATION CLIENT, EVENT, TRIGGER ON *.* TO 'dba'@'localhost'; > GRANT LOCK TABLES ON *.* TO 'dba'@'localhost'; > FLUSH PRIVILEGES; Setup a backup script!
