Schema on read with runtime fields

Elastic

Elasticsearch has always been fast, but required structuring and indexing your data up front. We're changing that with the introduction of runtime fields, which enable you to extract, calculate, and transform fields at query time. They can be defined after data is indexed or provided with your query, enabling new cost/storage/performance tradeoffs, and letting analysts gradually define fields over time.
