Do I need a search engine for logs and events?

Not always.
You need a search engine for logs and events if you want to do any of these at scale:
- Fast full-text search across lots of records
- Filtering and aggregating by many fields
- Near real-time querying over high-volume data
- Troubleshooting and observability with interactive exploration
- Indexing so queries don’t scan raw files every time
Typical choices: Elasticsearch / OpenSearch, Splunk, Datadog Logs, Loki (with labels + log store), etc.
You may not need a search engine if:
- Your log volume is small
- You only need simple retention and occasional lookup
- You mainly do batch analysis with SQL/Parquet in a data lake
- You’re okay with object storage + indexing/metadata via another system
- Logs are mostly for compliance/archival, not interactive search
A good rule of thumb:
- Operational debugging / SRE use case → search engine is usually worth it
- Archive / audit / low-volume analytics → plain storage may be enough
If you want, I can help you decide based on your setup (volume, retention, query patterns, budget).
