Storage
fake_dynamo stores the write operations (request that changes the
data) in /usr/local/var/fake_dynamo/db.fdb and replays it before
starting the server. Because of the way fake_dynamo stores the data,
file size tend to grow by time. so fake_dynamo will compact the database
during start up if the file size is greater than 100mb. you can
manually compact it by passing –compact flag.
