The CDC_users.md document was not linked to and was in the wrong place. It should reside in the protocol directory since it relates to the CDC protocol.

# Change Data Capture (CDC) users
|
|
|
|
Change Data Capture (CDC) is a new MaxScale protocol that allows compatible
|
|
clients to authenticate and register for Change Data Capture events. The new
|
|
protocol must be use in conjunction with AVRO router which currently converts
|
|
MySQL binlog events into AVRO records. Clients connect to CDC listener and
|
|
authenticate using credentials provided in a format described in the [CDC Protocol documentation](CDC.md).
|
|
|
|
**Note**: If no users are found in that file or if it doesn't exist, the only
|
|
available user will be the _service user_:
|
|
|
|
```
|
|
[avro-service]
|
|
type=service
|
|
router=avrorouter
|
|
source=replication-service
|
|
user=cdc_user
|
|
password=cdc_password
|
|
```
|
|
|
|
## Creating new CDC users
|
|
|
|
```
|
|
bash$ cdc_users [-h] USER PASSWORD
|
|
```
|
|
|
|
The output of this command should be appended to the _cdcusers_ file at
|
|
`/var/lib/maxscale/<service name>/`.
|
|
|
|
```
|
|
bash$ cdc_users user1 pass1 >> /var/lib/maxscale/avro-service/cdcusers
|
|
```
|
|
|
|
Users can be deleted by removing the related rows in 'cdcusers' file. For
|
|
more details on the format of the _cdcusers_ file, read the [CDC Protocol documentation](CDC.md).
