What are the advantages and disadvantages of Elasticsearch?

Elasticsearch is a distributed search and analytics engine based on Lucene.

Advantages:

• High speed full-text search and analytics
• Horizontal scaling and fault tolerance
• Flexible data schema and JSON support
• Rich API for integration

Disadvantages:

• Requires significant resources for large data volumes
• Complexity in setup and optimization for beginners
• Possible data consistency issues in distributed operation

In Go projects, Elasticsearch is often used for fast search and aggregations, but it is important to consider the load and properly configure the cluster.
