How do you handle zero-downtime database migrations with 90+ custom schema tables in MySQL 8.0?

Looking for architectural feedback on isolating table updates with lock-free delta indexes. Ran the AI Review Copilot and received solid actionable hints on MySQL 8.0 algorithmic alter statements.

SQL
-- Online DDL with algorithm=instant where supported
ALTER TABLE wp_uniteelements_community_posts
ADD COLUMN ai_review_data LONGTEXT NULL,
ALGORITHM=INSTANT;


Any thoughts on handling legacy MariaDB 10.4 instances without instant DDL?
