The major release of MongoDB Database, v5.0 was launched on July 13, 2021. The arrival of the latest version of the MongoDB Database marks the commencement of a technical revolution. The novel features stunned data science MongoDB developers and lured many freshers to learn MongoDB Database. Mongo DB is a document-oriented database that is used for storing large volumes of data. Instead of utilizing tables and rows, MongoDB Database utilizes collections and documents. Documents contain key-value pairs that are the basic units of data in MongoDB. Collections, on the other hand, contain sets of documents and functions that are equivalent to relational database tables. MongoDB Database provides comprehensive management of all database services, including configuration, maintenance, security, backup, and scalability. This provides MongoDB developers the freedom to focus on providing exemplary features for the applications. Top Features of MongoDB 5.0 The latest version of MongoDB removes friction and complexity from the developer’s end and enables them to craft innovative and highly scalable solutions rapidly for a wide range of use cases. Native Time-Series Features One of the most awaited features that MongoDB 5.0 brought to the board is first-class support for time series data. While some MongoDB developers have developed their time series tooling around MongoDB Database, having a time-series feature natively will assist many more developers to hit the ground running. A “time series” refers to a kind of data where records are created at different periods of time in a sequence. The general use cases of time series include – sensor measurement streams and transaction history logs, where each record corresponds to a particular moment. New time-series collections provide a special data store that is optimized for data with these characteristics. Values can be compacted into a unique schema structure when persisted to disk, providing enhanced indexing, more efficient storage use, and reduced server load. With, native time series, one can set the granularity of time data to seconds, minutes, or hours. It is also possible to expire data after a set number of seconds. Live Resharding One of the biggest challenges with horizontal scaling MongoDB Database has been its approach to sharding. It is crucial to choose the correct shard key to your cluster’s performance. However, this was previously a one-way operation. Once one would set the key, it can’t be changed. Further, leaving one powerless if any wrong decision is made on day one. MongoDB Database 5.0 puts an end to shard key nightmares. If one gets it wrong, collections can be re-indexed utilizing a new shard key. The latest version of MongoDB Database will handle the entire migration, without causing any downtime. This makes it easier to escape subpar performance caused by incorrect shard configuration.
