Enrich your Elasticsearch documents with Logstash
Blog post from Elastic
The article by David Pilato discusses how to enhance Elasticsearch documents using Logstash, particularly when dealing with complex tasks or data sources outside of Elasticsearch. While the Elasticsearch Enrich Processor can handle data enrichment within an ingest pipeline, Logstash offers a more adaptable solution, especially when data needs to be stored in both Elasticsearch and a third-party system. Pilato explains a pipeline setup for enriching documents with Logstash, noting its ease but also its initial slow performance due to network lookups. He introduces a faster method using a static JDBC filter and the Elasticsearch JDBC Driver, which significantly reduces execution time by caching the data in Logstash, thus optimizing the enrichment process. This approach is beneficial for small Elasticsearch indices that fit within Logstash's JVM memory, although larger datasets may still require the Elasticsearch Filter Plugin. The article concludes by hinting at future discussions on using the Elastic Agent for similar enrichment tasks.
