Study Notes
- There are various factors to consider when choosing the number of cores for your database system.
- High-frequency core is preferred for OLTP workloads to provide better process latency and achieve good database performance.
- Open-source databases like MySQL and PostgreSQL do not scale well with core increasing due to their code limitation, so you could choose the correct number of cores that suits you best.
- Intel solutions enhance Database storage. Intel Optane SSD and Intel PMEM act as new storage hierarchies between DRAM and NAND SSD, improving the data access latency for your database system.
- Intel Storage Performance Development Kit (Intel SPDK) provides tools and libraries for writing high-performance, scalable, user-mode storage applications.
- Indexing makes columns faster to query by creating pointers where data is stored within a database. As a result, it speeds up the time it takes to search and find data in SELECT queries.
