Why do we store logs in Elasticsearch instead of a regular database?

Elasticsearch is optimized for storing and quickly searching large volumes of unstructured data, such as logs. Unlike traditional relational databases, it provides:

• Fast full-text search and aggregations on logs.
• Horizontal scaling to handle large data streams.
• Flexible schema, which is convenient for various log formats.
• Built-in visualization and analysis capabilities (e.g., through Kibana).

Regular databases are less effective for such tasks due to limitations in search speed and scalability.
