One New Idea

• Caching to an extreme

• TimesTen makes an in-memory RDBMS

• Cache commonly used data in application server

• Preserve SQL interface

• Reduce contention on underlying DBMS

• Updates

  • On the Web, not all interactions critical
  • Some updates need not be durable (e.g., user currently logged in)
  • Other updates can still be logged & propagated
