copy large number of files in s3 to a large mysql table. the columns for the mysql table will be a few columns for the metadata of the file and then a large text column that contains all the data in the file.
Because there may very large number of files, a complete solution will be the one that makes sure it gets every file and that there is a way to check that its gotten every file.
also sharding of the mysql database into several servers may be necessary because of large size of the data. Persons with demonstrated experience in s3 data handling need only apply. Experience with continuous integration is a big plus.
