Elasticsearch index templates automatically apply settings to new indices based on patterns.

Elasticsearch offers Data Streams for simplicity and Time-Based Indices for control in managing time-series data.

The dual-write trap in Elasticsearch can cause data inconsistency during reindexing.

You can update Elasticsearch indices without downtime using alias switching.

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

Elasticsearch aliases allow zero-downtime switching between indices for applications.

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

Elasticsearch uses shards for data distribution and replicas for redundancy.

The Transactional Outbox Pattern ensures database updates and event publishing are synchronized to avoid losing events.

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

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

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

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

Elasticsearch Data Streams simplify time-series data management with one name for many indices.

A document in Elasticsearch isn't searchable right after it's saved due to the refresh process.

Choosing the right distributed lock depends on your system's needs and existing tools.

Redis is a fast in-memory data store used for caching and low-latency applications.

Microservices are useful when you need independent scaling, deployment, and clear boundaries in software design.

Database per Service ensures each microservice owns its data, reducing dependencies.

The number of Elasticsearch nodes depends on storage, workload, and performance needs.

Choosing the right boundaries for microservices is crucial for effective architecture.

The USE Method helps find and analyze infrastructure bottlenecks in software systems.

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