MongoDB Charts offers the best way to create visualizations using data from a MongoDB database. MongoDB Charts is a new, integrated tool in MongoDB for data visualization. It also automatically incorporates error handling logic for "TransientTransactionError" and"UnknownTransactionCommitResult". It starts a transaction, executes the specified operations, and commits (or aborts on the error). Call-back API: This is the recommended approach to using transactions.Core API: It is a similar syntax to relational databases (e.g., start_transaction and commit_transaction).MongoDB provides two APIs to use transactions. Transactions provide a useful feature in MongoDB to ensure consistency. What do you mean by Transactions?Ī transaction is a logical unit of processing in a database that includes one or more database operations, which can be read or write operations. To insert a single document, use the collection’s insertOne method: > db.books.insertOne() The basic method for adding data to MongoDB is “inserts”. Sharding: Sharding is the process of splitting data up across machines.File storage: It supports an easy-to-use protocol for storing large files and file metadata.Special collection and index types: It supports time-to-live (TTL) collections for data that should expire at a certain time.Aggregation: It provides an aggregation framework based on the concept of data processing pipelines.Indexing: It supports generic secondary indexes and provides unique, compound, geospatial, and full-text indexing capabilities as well.Each sharded cluster must have its own config servers. MongoDB uses the config servers to manage distributed locks. The mongos acts as a query router, providing an interface between client applications and the sharded cluster.Ĭonfig servers store metadata and configuration settings for the cluster. It then redistributes documents automatically. Balancing and loading data across a cluster is done by MongoDB. The document-oriented data model of MongoDB makes it easier to split data across multiple servers. What are some utilities for backup and restore in MongoDB?
