Database bottlenecks slow down performance, but identifying them helps optimize and scale effectively.

Cache breakdowns can overwhelm databases, but request coalescing solves this issue.

An inverted index helps search engines quickly find documents containing specific terms.

Elasticsearch distributes search queries across shards to find and retrieve results quickly.

Choose Elasticsearch for complex text searches, but use databases for structured queries.

Cache penetration occurs when requests for non-existent data overload the database.

Search engines collect, index, retrieve, and rank documents to provide relevant results.

Elasticsearch fuzzy search allows finding results even with typos in queries.

Caching helps applications respond faster by serving data from memory instead of hitting the database.

The Cache-Aside Pattern speeds up data retrieval by using a cache to store frequently accessed data.
