TFRecords and record shuffling
<p>My understanding is that it is good practice to shuffle training samples for each epoch so that each mini-batch contains a nice random sample of the entire dataset. If I convert my entire data-set into a single file containing TFRecords then how is this shuffling to be achieved short of loading the entire data-set? My understanding is that there is no efficient random access to TFRecord files. So, to be specific, I am looking for guidance as to how TFRecord files are used in this scenario.</p>
