DynamoDB Dynomite Deleting

Important: These docs are for the outdated Jets 5 versions and below. For the latest Jets docs: docs.rubyonjets.com

Destroy

Will run callbacks:

post = Post.find_by(title: 'post 1')
post.destroy

Delete

Will bypass callbacks:

post = Post.find_by(title: 'post 1')
post.delete

Batch Deleting

The delete_all deletes without running callbacks and also uses batch_write_item to delete faster.

Post.delete_all

You can scope it with normal relation querying.

Post.where(title: "post 1").delete_all
Post.limit(2).delete_all

You can also use delete_by to do the same thing:

Post.delete_by(title: "post 1")
Post.limit(2).delete_by(title: "post 1")

Batch Destroying

There are also the corresponding destroy_all and destroy_by methods, which will run callbacks.

Post.destroy_all
Post.destroy_by(title: "post 1")
