PostgreSQL’s past topics

• Performance– No problem. Excellent.

• Scalability (Scaling up & Scaling out)– PostgreSQL works well on 16-way SMP.– We have some scaling-out replication solutions.– A built-in replication is coming. (Thanks hackers!)

• Availability– We have a warm-standby feature.– Also we have some replication solutions.

• Vacuum– We have a “HOT” feature.

PostgreSQL’s next topic is…

Monitoring

&

Administration

(just my opinion)

“Cloud” Generation Computing

• Lots of servers

–Multi-core processors

– Commodity (cheaper) hardware

• Lots of software

–We love OSS!

• … needs lots of admins?

“Cloud” Generation Administration

• “Cloud” is a datacenter-centric architecture.

• In “Cloud” generation, we have to do many

admin tasks on many virtual/physical servers and many software, with fewer admins.

• So “Monitoring and Administration” is the key

to the next generation infrastructure.

Monitoring and Administration requirements

• We need to monitor and check…– Processor and memory usage

– Database size and I/O traffics

– Cache hit ratio

– Transactions and backend activity

– Slow queries

– etc, etc, …

I want to do them easily on many servers and software.
