Beyond 10,000 Fields: Balancing Performance and Cost in Wide JSON with Apache Doris 4.1

Beyond 10,000 Fields: Balancing Performance and Cost in Wide JSON with Apache Doris 4.1

Managing schema-evolving datasets with thousands of dynamic keys presents severe metadata bloat and ingestion bottlenecks. This guide explores how Apache Doris 4.1 solves the wide-JSON problem using DOC mode (deferred JSON shredding) and Storage Format V3 (on-demand metadata loading), delivering columnar performance with the ingestion speed of a document store. #ApacheDoris #WideJSON #DatabaseArchitecture #OLAP #DataEngineering #SRE #BigData #Observability #StorageEngine #VeloDB
