Study Notes
- Relational databases are based on the relational model, strictly adhering to a-to-mi-city, consistency, isolation, and durability properties - which we call ACID.
- Mainframe databases are outdated and expensive, while RISC+ DiskArrays and Hyper-converged Database appliances are more affordable but compromise on scale-up performance.
- Middleware-based sharding is used for scale-out, but requires many code changes to the application.
- NewSQL databases like Google Spanner were invented to support distributed and multi-model features.
- In-Memory Data Grid is the future direction of Databases, and memory resources can be more easily pooled, accelerating the design and deployment of IMDG in the cloud.
- Database optimization is an important part of keeping a database running at its best.
- There are many aspects to database optimization, including architecture, hardware, application, and database engine aspects.
- One way to improve database performance is by using an in-memory cache as a data layer between applications and databases.
- Separation of storage and compute can also help improve database performance.
- The Intel 3rd Xeon scalable platform processor is a good choice for database performance because it has more cores and higher frequency.
