Both MongoDB and DolphinDB are databases of big data. But there is a big difference between the two. The former is a document-based NoSQL database, which can be used to process unstructured and structured data, and can quickly find or write documents according to key values. The latter is a multi-model database with column storage, which is mainly used for high-speed storage, query and analysis of structured time series data. MongoDB has its own most suitable application scenarios. However, there is a lack of excellent big data products in the market, and many users try to use MongoDB to store and query structured time series data in the fields of Internet of Things and finance.
