In 2015, Correios de Portugal, the recently privatized Portuguese postal company, created Banco CTT, its own private banking company operating out of its own post offices.

Therefore, despite its youth, Banco CTT manages high business figures: at the end of 2022, it has more than 600,000 open accounts, more than 800,000 customers and around 2.3 billion euros in deposits.

Banco CTT has an email notification system, which controls the number of notifications generated and the changes of residence of a high volume of customers. The processing of this data must comply with certain legal requirements that pose an additional challenge to the tool.

To be efficient and, at the same time, solve the legal problem derived from the processing of the information, it is necessary to process all the information within a certain period of time.

Using a new database engine that meets some requirements:

• That provides the intended real time view
• Easy to integrate
• Ready for future growth
• With a low TCO

LeanXcale is optimal, as it fulfills all these conditions.

LeanXcale enables, in production, real-time analysis and visualization of all available information. Stress tests show that the system allows a continuous load of more than 10 times the current load with full historical and parallel queries.
