Accelerated Database Recovery is in Standard Edition. This way your memory limit is based on how much you spent on licensing, not some arbitrary limit decided in a conference room somewhere 5 years ago. But what if I've already done that on another system with the same workload? Parting Thoughts.

A Cassandra database cluster had switched to Ubuntu and noticed write latency increased by over 30%. CLI tools The Cassandra systems were EC2 virtual machine (Xen) instances. top(1) showed that only the Cassandra database was consuming CPU. Microbenchmark os::javaTimeMillis() on both systems. But I'm not completely sure.

There were so many interesting papers at the conference this year though that I haven’t been able to cover nearly as many as I would like. MongoDB is an important database, and this paper explains the tunable (per-operation) consistency models that MongoDB provides and how they are implemented under the covers. Industry papers.

A resilient system continues to operate successfully in the presence of failures. The system needs to maintain a safety margin that is capable of absorbing failure via defense in depth, and failure modes need to be prioritized to take care of the most likely and highest impact risks. The first technique is the most generally useful.

For example, changing our database architecture to be more efficient could save on server costs. In his recent Smashing Conference talk, green software expert Asim Hussain mentioned that the biggest shift he is seeing is as a result of regulation — or the threat of regulation.
