The CheckS3Existance.py and theCopyS3ToNewBucket.py scripts are used to check if a file exists in an S3 bucket.

This is useful for copying files from one bucket to another, or for checking if a file exists before downloading it. You can also use these scripts to move dockets to smaller bucket when ingesting data into OpenSearch.

To copy a file from one bucket to another, call the copy_s3_folder_boto3(folder) function in the CopyS3ToNewBucket.py script. This function takes the name of the folder you want to copy as an argument. Please note that script will only copy files from the mirrulations bucket to the new bucket.

Example:

copy_s3_folder_boto3('ACUS-2010-0001')

To check if a file exists in an S3 bucket, call the check_s3_file_exists(bucket, key) function in the CheckS3Existance.py script. This function takes the name of the bucket and the key of the file you want to check as arguments.

Example:

check_s3_file_exists('mirrulations', 'ACUS-2010-0001/')
