Database company, MySQL, has upgraded its offerings an a version 8.0 update.
Key new features in MySQL 8.0
Improved JSON Support:

“The MySQL document store allows you to treat MySQL like a document database, with a set of NoSQL CRUD APIs to access your data. First introduced in MySQL 5.7, the document store now provides you with consistent reads-and-writes. This gives it a distinct advantage over other NoSQL databases, in that developers don’t need to give up transactional semantics. Data created in the Document Store can also be accessed via the regular MySQL SQL protocol.” describes MySQL in the blog article.
- Indexing capabilities for the new document store feature is also getting an improvement from previous 5.7 capabilities.
- Support for spatial indexing of GeoJSON data inside of a JSON document
CTEs and Window Functions:
- MySQL has implemented recursive queries or Common Table Expressions(CTEs) as well as Window Functions
- Unicode support has been updated to 9.0
Better Handling of Hot Rows:
- New Lock modifiers “SKIP,” “LOCKED,” and “NOWAIT” has been implemented.
“It is becoming more common for MySQL to be deployed in a virtual machine, where the amount of system resources can change as the system is scaled up or down. With the new innodb_dedicated_server option, it’s possible to auto-detect the system memory, and have MySQL adjust appropriately without having to edit configuration files.” says MySQL.
