A rapid parallelized AWS S3 key & bucket deleter.
I was recently tasked with deleting an bucket in Amazon's Simple Storage Service (S3) that contained an absolutely massive number of files.
Unfortunately, Amazon themselves do not give you an easy way to do this yourself. Their web interface stalls indefinitely when you delete an "adequately large" number of files, and their CLI tool (aptly named "aws-cli") only deletes files in a single-threaded fashion (i.e. slowly).
After googling around a bit, I encountered s3nukem (itself a fork of s3nuke), which appeared to be the solution to my problems. After a few minutes of trying to find the 'right' version of RightAWS (the s3nukem code & readme had a disagreement over this), I was able to get it up and running. However, after a bit of back-of-the-napkin math, it was looking like it was still going to take at least a month of running s3nukem before the bucket was deleted.
So, I wrote s3wipe. S3wipe, as far as I know, is the only S3 key/bucket deletion tool that:
- Does parallel, thread-based delete AND list operations (more speed)
- Performs batch deletes (MOAR SPEED!)
- Will delete versioned objects (MOAR... well, deletes)
Using s3wipe, I was able to delete 400 million S3 objects in about 24 hours.
This is just a single-file script, so just go ahead and run it. It will need a semi-recent version of the "boto" python module to be installed, though, so:
pip install boto
yum install python-boto
apt-get install python-boto
wget https://raw.github.com/eschwim/s3wipe/master/s3wipe chmod 755 s3wipe
Clone the repo:
git clone email@example.com:eschwim/s3wipe.git cd s3wipe
Build the Docker image:
docker build -t s3wipe:latest .
Then run the script:
docker run s3wipe:latest --help
usage: s3wipe [-h] --path PATH --id ID --key KEY [--dryrun] [--quiet] [--batchsize BATCHSIZE] [--maxqueue MAXQUEUE] [--delbucket] Recursively delete all keys in an S3 path optional arguments: -h, --help show this help message and exit --path PATH S3 path to delete (e.g. s3://bucket/path) --id ID Your AWS access key ID --key KEY Your AWS secret access key --dryrun Don't delete. Print what we would have deleted --quiet Suprress all non-error output --batchsize BATCHSIZE # of keys to batch delete (default 100) --maxqueue MAXQUEUE Max size of deletion queue (default 10k) --delbucket If S3 path is a bucket path, delete the bucket also
You can now delete all keys under an arbitrary S3 path, instead of only entire buckets (although that is still an option, as well).
