Finding the Best Practices for long alter table queries

Question

Hi,  
With Aurora what is the best practices to perform long alter table operations without downtime?  
Is there equivalent of pt-online-schema-change which can run alter table without locking ?

Answer

Sure, you could use percona tool for alter table.  
  
you could find reference as below link.

But I recommend that you could use gh-ost for that. it is trigger-less which I think much better than percona online schema change tool. I have tested and it works fine with aurora 5.6 & 5.7

Hope  this could solve your problem.
