# concurrent-mysql
Evaluating different strategies for handling concurrent updates.
1. Create this table in MySQL:
``` sql
CREATE TABLE `T` (
`id` bigint(20) unsigned NOT NULL AUTO_INCREMENT,
`count` int(11) DEFAULT NULL,
PRIMARY KEY (`id`),
UNIQUE KEY `id` (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;
```
2. Adjust script values numConcurrent and strategiesToTry.
3. Run with `DB_PASSWORD=password node index.js` and examine output for which
strategies were correct or incorrect.
