无法修改 binlog_format 的默认参数组

Question

Using RDS Aurora cluster with engine 5.6.mysql_aurora.1.22.2 in AWS with a writer instance(us-east-1a) and a replica instance db.t3.small (us-east-1b).

I'm trying to change the default parameter group for binlog_format from OFF to ROW, but I'm having this error:

Error saving: Cannot modify a default parameter group. (Service: AmazonRDS; Status Code: 400; Error Code: InvalidParameterValue; Request ID: 4571b2e7-02c2-454a-9a21-062a8ffa66a5; Proxy: null)

Any thoughts?

Answer 1

In order to change a setting in the parameter groups, you will need to create a new custom parameter group, and then change the binlog_format parameter in there.

Once that's saved, you'll be able to change the RDS instance over to the new parameter group. Rebooting will make the parameter group take affect. Be aware of any downtime from rebooting your instance.

I'm currently trying the same, and have referenced this article: https://aws.amazon.com/premiumsupport/knowledge-center/enable-binary-logging-aurora/ .
