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

Partitioning and indexing are great, but have you tried columnar storage? Tools like Apache Parquet or ClickHouse optimize data retrieval by storing data column-wise instead of row-wise.

For massive datasets, this can be a game-changer—way faster for analytical queries. Also, consider pre-aggregating data if you don’t need raw precision.

NoSQL can be messy for complex queries, but it’s killer for simple key-value lookups. Maybe hybrid approach?
