Advanced Kibana concepts
Kibana has several implementations that are designed for very specific use case requirements, and runtime fields is one of them. Let’s explore and understand them.
Runtime fields
Forget static schemas; Elasticsearch runtime fields are your dynamic paintbrushes! They let you create fields on the fly, transforming your data on demand within your queries. Imagine a data sculptor, molding your documents with temporary fields based on your needs.
There’s no need to re-index or restructure your data. Runtime fields are calculated at query time, pulling information from existing fields or even combining them into new ones. Think of it as a temporary data transformation, enriching your documents without changing their core structure. These dynamic fields are versatile. You can extract specific values using Grok patterns, calculate aggregates such as averages or counts, or even perform complex calculations. They’re perfect for adding context...
