Vespa with Logstash Recipes

The blog post by Radu Gheorghe explores the integration of Vespa and Logstash, illustrating how Logstash, an ETL tool, can efficiently feed data into Vespa, a versatile search engine, despite not being optimal for log searches. The post provides detailed recipes for various scenarios, such as feeding data from CSV files, databases, and Kafka into Vespa, as well as migrating data between Vespa clusters and from Elasticsearch to Vespa. It highlights the use of Logstash's plugins for input and output transformations, including the handling of metadata and the setup of reliable data pipelines with dead letter queues for error management. The guide emphasizes how Logstash can serve complex processing needs, which, combined with Vespa's capabilities, offers robust solutions for enterprise search, recommendations, and more.
