Oh, and there’s a scheduler too of course to keep all the plates spinning. On the Cloudburst design teams’ wish list: A running function’s ‘hot’ data should be kept physically nearby for low-latency access. A low-latency autoscaling KVS can serve as both global storage and a DHT-like overlay network.

The main reason behind this is that MySQL is a relational database system (RDBMS), and any data that is going to be written in it must respect the RDBMS rules.

As we said at the time, DynamoDB was a result of 15 years of learning in the area of large scale non-relational databases and cloud services. Based on this experience and learning, we built DynamoDB to be a fast, highly scalable NoSQL database to meet the needs of Internet-scale applications. Fully managed cache for DynamoDB.

It is very common to have large resource-hungry databases separated across nodes using anti-affinity rules. As with traditional storage, applications are writing to a shared storage environment which is necessary to support VM movement. The key thing to observe is the impact on the latency sensitive (OLTP) workload.

A then-representative $200USD device had 4-8 slow (in-order, low-cache) cores, ~2GiB of RAM, and relatively slow MLC NAND flash storage. Not as much as we'd like, of course, but the worldwide baseline has changed enormously. There are differences, of course, but not where it counts. The Moto G4 , for example.

Estimated Input Latency tells us if we are hitting that threshold, and ideally, it should be below 50ms.

This approach often leads to heavyweight high-latency analytical processes and poor applicability to realtime use cases. The straightforward approaches for implementation of this system are: Log all events in a large storage like Hadoop and compute unique visitor periodically using heavy MapReduce jobs or whatever.
