The MyISAM merge tables function proved to speed up performance significantly. The BBC wanted to work in real-time with a dynamic system which would give audiences a real sense of the news stories on the website being selected most by other users.
35 million unique users and receives over 800 million page impressions each month. Being a mature solution, it supports JOIN, atomic transactions with privilege and password security system. If you’ve fixed schema and a data structure aren’t going to change over the time like Wikipedia. If you’re just starting and your database is not going to scale much, MySQL will help you in easy and low-maintenance setup.
As such, there is no “standard” benchmark that can help you with the best database to use for your needs. Only your demands, your data and infrastructure can tell you what you need to know. Thus the use of intelligent sharding keys or hashed sharding keys is critical. Also, sharding key changes can have a knock-on effect on application, data location, and transactionality across nodes.
Therefore, by loading all data from the table row, you end up bringing five times more data than you actually needed for that screen. The greatest value they bring is SQLite abstraction, letting us map database entities to Java objects relatively easy. These are, in fact, some of the out-of-the-box benefits we get with Realm, a database platform with a distinct architecture, which has emerged as a new alternative to SQLite. Since Android was created, we app developers have been using SQLite to store our local data. Sometimes directly with SQL statements, sometimes using an Object-Relational Mapper as an abstraction layer, but either way, we’ve been using SQLite at the end of the day.

The results you get from a query are actually just pointers to the real data. Say you have a table with 15 columns, and in a certain screen of your app, a list of objects from this table is displayed.

Carnality – Choose a shard key which is easy to split later if the database size is exceeding chunk size. Like MySQL, MongoDB sharding has the ability to perform range-based data partitioning. MongoDB also supports automatic data volume distribution and transparent query routing. Horizontal scaling includes dividing the dataset and load over multiple additional servers. Each machine handles a part of the workload with a comparatively lower cost than high-end hardware for a single machine.
