- Blobs should be stored in a separate tablespace because:
- Selects on the table would need to go over the blob data as well even though the blob is not selected in the clause.
- Setting CACHE on the DDL for blobs is beneficial when the blob data is read a lot but does not help in inserts.
- Truncate table with drop storage option is preferable than delete from table since it does not generate logs. Note that this is a DDL operation and does not lead to any logs being generated.
- Partitioning is a way to maintain huge data sets with lots of advantages rather than just regular tables.
