It looks like this is a creative way of making sure nobody else writes their own software for talking to Oracle databases -- to do that, you would have to copy the poem, which is a violation of Oracle's copyrights.

Make sure related data is put into the same bucket

• Assign related items to the same data partition
  • e.g. chunks of the same file, audio spoken by the same person etc

This will make sure your network has been contaminated by seeing testing samples during the traing phase.

e.g. the following function from tensorflow examples assigns files stably to partitions, ignoring a regex in the file name:

Implemented using typeclasses.

Implementation:

1. Define the problem with types :

• Encoder[A] & Decoder[A]. Encoder takes an A, and produces an AttributeValue. Decoder does the opposite.
• KeyLike[A] coproduct for things that can be keys.
• NamedKeyLike[A] a key that has a name, an encoder, and a decoder.
• PrimaryKey - I suppose it's the Primary Key of the table
