insertMany

insertMany is a Change Type in the Liquibase Open Source and Liquibase Pro extensions for MongoDB that inserts multiple documents into a collection.

Uses

The Liquibase Pro extension for MongoDB includes several modeled Change Types from the Liquibase Open Source version. These let you specify a few MongoDB commands using Liquibase XML, JSON, and YAML changelogs.

insertMany is one such Change Type. You can use it to insert multiple documents into a collection in your database.

If you just want to insert a single document, use insertOne instead.

Note: If you want to specify mongosh statements in your XML, JSON, and YAML changelogs, use the mongo and mongoFile Change Types instead.

Run

To run this Change Type, follow these steps:

  1. Add the Change Type to your changeset, as shown in the examples on this page.

  2. Specify any required attributes. Use the table on this page to see which ones your database requires.

  3. Deploy your changeset by running the update command: liquibase update

Available attributes

For more information, see db.collection.insertMany().

Tip: You must specify all top-level attributes marked as required. If you specify an optional attribute, you must also specify any nested attributes that it requires.
