To meet the demands of online applications, the databases must be capable to manage always more information and ever more rapidly. In this context, NoSQL databases have got their place beside relational databases. Here are the main differences induced by this search of performance. 1. In memory vs SSD A relational database constantly records [...]
1. Hashtable A hashtable is a solution for associating keys with values. Its success comes from its speed. To work, a hashtable computes a hashcode for each key. This hashcode is used to designate the location where the key-value pair is stored in the table. To disperse the data inside the table, the hashcode is [...]
The NoSQL databases implement various techniques to meet the need for even faster access to (big) data: the asynchronous API is one of them. Let's be down to the earth: to store or retrieve information, the client application exchanges data with the NoSQL database through a roundtrip made of 3 main stages: command sending / [...]
