Discussion with Edinburgh people

 

Understanding where the data is, and how to access the closest data in the job

Metadata and trigger records across multiple files.

 

Challenge, how do we store thousands of integer numbers associated.

List of integers is allowed but may not scale well for syncing.

 

List are not scary anymore.

Indices will be comparable in size to the table itself

But not bigger than the data.

 

Look at the metadata schema, Igor shares
