Core Elasticsearch Training in Singapore

Exposure to or interest in Elasticsearch, relational databases, distributed systems, or information retrieval.

Developers who would like to build real-time search solutions and analytics solutions.

The course aims to provide a solid foundation in search and information retrieval. Starting with fundamental concepts and covers best practices, key features, and distributed search application development with Elasticsearch.

During the course there will be time for discussion as well as attendee case studies. At the end of the training you will have an in-depth understanding of how Elasticsearch works, you will be able to reliably analyze, understand, and solve common problems, and be ready to build state-of-the-art search applications.
