TIL: Drop Columns a Release Later
Recently, I worked on a database migration at work where I had to plan a database migration rollout across releases to avoid downtime. For this, I applied the expand and contract pattern, even though, at the time, I didn't know there was a name for it. I now realize, though, that the contract phase should've gone out in two phases.

Fix Amazon Aurora MySQL error 63955: Virtual index ID overflow
An Amazon Aurora MySQL cluster can exhaust its virtual index ID limit, after which any CREATE INDEX that includes a virtual column fails with error 63955 until you rebuild the databases. This post shows how to recognize the error, why backups cannot clear it, and how to run a logical dump-and-restore migration with monitoring to catch it next time.

This post shows how to read DB load in Amazon CloudWatch Database Insights, interpret the most common MySQL wait events, and turn each into a concrete action, so you can fix the real bottleneck instead of scaling up to a larger instance.
