AWS DMS target endpoint extra connection attributes format

Question

There is no example in documentation how to define Extra connection attributes for target endpoint in case you have more than one settings. I have to set for MySQL:
SET FOREIGN_KEY_CHECKS=0 and SET time_zone='+00:00'. 
In DMS console they are defined as:

```
Initstmt=SET FOREIGN_KEY_CHECKS=0,time_zone='+00:00';
```

I'm not sure if that bot settings are working. I'm not sure if a Initstmt should be initstmt and what is separator: ',' or ';' or something else. Does every settings inside 'initstmt' should start with 'SET'?

Answer

Hi,

It sounds like you will need to utilize "AfterConnectScript" as mentioned here. [1] 
> Alternatively, you can use the AfterConnectScript parameter of the --my-sql-settings command to disable foreign key checks and specify the time zone for your database.

I was able to create an endpoint with 
` "AfterConnectScript": "SET time_zone=+00:00",`
and
`Initstmt=SET FOREIGN_KEY_CHECKS=0;`
