I don't seem to find any document about deleting S3 objects based on the object size. For example if an object size is less that 5B then delete it.

Yes, it is possible to delete an S3 Object based on size.

One workaround is to get the Object size of the S3 bucket via AWS CLI ( you can use cli or boto3 ) and performing a cron job that will perform the condition when true if the object size is less than 5B.

The DeleteObject() API call does not accept parameters such as Size or ModifiedDate.

Instead, you must provide a list of object(s) to be deleted.

If you wish to delete objects based on their size, the typical pattern would be:

• Call ListObjets() to obtain a listing of objects in the bucket (and optionally in a given prefix)
• In your code, loop through the returned information and example the object size. Where the size is smaller/larger than desired, add the Key (filename) to an array
• Call DeteleObject(), passing the array of Keys to be deleted
