Apache CouchDB
The Apache CouchDB database was first released in 2005 by the Apache Software Foundation. Erlang is used to create CouchDB. It’s an open-source database that stores, transfers, and processes data in various formats and protocols. It stores data in JSON, executes queries in JavaScript using MapReduce, and provides an API through HTTP. CouchDB is well-suited to current online and mobile applications. Using CouchDB’s incremental replication, you may efficiently disseminate your data. CouchDB allows for master-master configurations with automatic conflict detection. CouchDB has several capabilities that make web development more straightforward, such as on-the-fly document transformation and real-time change notifications. It even has a simple web administration panel that is supplied directly from CouchDB! It is a high-availability, partition-tolerant database that is also eventually consistent. It offers a fault-tolerant storage engine that prioritizes data security. Excellent tolerance to overhead, expensive arbitrary queries, prolonged temporary views on large datasets, absence of support for transactions, occasional failure of replication of large databases are some of the shortcomings of CouchDB.
