mongoimport

Mongoimport is a command-line tool provided by MongoDB for importing data from various file formats into MongoDB databases. Using mongoimport, you can efficiently insert large amounts of data into your MongoDB collections from JSON, CSV, TSV, or BSON files.

This tool offers several options to customize the import process, such as specifying the database and collection to import the data into, defining the file format, and mapping fields in the input file to fields in the MongoDB document. Additionally, you can control the behavior when encountering duplicate entries or errors during the import.

Mongoimport provides support for importing data from remote databases through the use of the --uri option or by specifying connection details directly in the command. It also supports authentication mechanisms like username/password and authentication databases.

You can use mongoimport to import data into both standalone MongoDB instances and replica sets. In the replica set scenario, mongoimport automatically redirects the import operation to the primary node to ensure data consistency.

This tool is particularly useful for initial data import, batch updates, or data migration tasks in MongoDB. It offers a straightforward and scalable way to load large datasets into your MongoDB collections efficiently.

Mongoimport is part of the MongoDB database server installation and can be accessed through the command prompt or terminal. It is among the efficient and commonly used tools within the MongoDB ecosystem for managing data import operations.
