What’s the most efficient method for data retrieval in large datasets? or How do you optimize data re

Honestly, it depends on your use case. For OLTP, stick with SQL and optimize your indexes. For OLAP, go columnar.

Ever tried materialized views? They’re like caching but built into the DB. Saves me tons of time on repetitive data retrieval tasks.

Also, check out Elasticsearch if you’re dealing with full-text or fuzzy searches.
