Expert tip

MySQL doesn't support some types of characters (such as emojis) with the utf8 encoding. You need to be on MySQL 5.5+ and force utf8mb4 (everywhere, client and server). You can do this sending the query "SET NAMES utf8mb4". Check this https://goo.gl/3E2qzg

Make sure you are using InnoDB storage engine and READ-COMMITTED transaction isolation level and increase the database server innodb_lock_wait_timeout variable to about 500.
