Mysql Innodbcluster using mysql-operator

[Ales Verbic]

Hi,

I am trying to move data from Mysql5.7 to MySql8.0.28 InnoDB cluster.

The first attempt was to use load data through router instance expecting to write to a single master. But I was hitting into a group_replication_transaction_size_limit=214748364 when I increased the group_transaction limit to the max. I got another error only packets smaller than 2135850104 can be compressed.

side note
mysqldump I didn't use --extended-insert=true --single-transaction=true.

I don't know what I was doing wrong.

On the second attempt I thought I could use clone but I figure it out that won't work as I need the same MySQL version.

What is the recommended way to load 50GB of data to InnoDB cluster?

Thank you,
Ales
