with a normal "serial", without "big", you can have 9.223.372.036.854.775.807 records individually numbered.
- Few tables but number of objects is tens-hundreds of thousands.
- less than 100 queries per second.
so you are talking about 10*100*1000=1000000 in words one million records? That is not very big.
Table: item
---------------------
account_id
item_id
So you have a combined primary key for item? That is technically totally correct, no problem.
Non the less I recommend to have a separate primary key column for item. As you are starting with databases, some things will be easier to do without having a combined key as primary.
How generally this design will hold up against this amount of data?
Insufficen data to parse "this amount" :) You did not give us any information about how WIDE your rows are. Some million records are nothing if there just hold social security numbers in them; they can get quite stressfull if every row carries 3 blobs containing Videos.
