Pooled tables are used to store internal parameters for Database parameters only and is always used for internal purposes - rarely you will have to create a pooled table for use in programs unless and until for DB Programs and DB data maintenance.
Pool Tables (match codes, look up tables)
Should be accessed via primary key or
Should be buffered (SE11->Display Table->technical settings)
No secondary indexes
Select * is Ok because all columns retrieved anyway
Hope the below link gives you an insight into how the pooled/cluster tables behave.

For better understanding on how and when to create pooled/cluster table, refer to the below examples.
All Condition tables i.e., Annn tables (pricing/discounts etc.,) belong to the table Pool KAPOL (Condition Pool) as the underlying concept is same across different condition tables, but, they have different Key (primary) fields.
Accounting Document Segment (Line Item records) BSEG is a cluster table that belongs to the table cluster RFBLG. Also, other tables such as BSEC, BSED, BSES, BSET also come under the same table cluster as all of them possess the common Key i.e., BUKRS/BELNR/GJAHR.
