dropCollection
dropCollection
is a Change Type in the Liquibase Open Source and Liquibase Pro extensions for MongoDB that removes a collection or view from the database.
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.
dropCollection
is one such Change Type. You can use it to drop an existing collection from your database.
Note: If you want to specify mongosh
statements in your XML, JSON, and YAML changelogs, use the mongo
and mongoFile
Change Types instead.
