PhonePe, a Walmart subsidiary and one of India's largest digital payment platforms, has adopted data observability to improve its massive data infrastructure. The company faced challenges in managing system performance due to the complexity of their OLTP (online transaction processing) and OLAP (online analytical processing). Acceldata played a crucial role in enhancing productivity by minimizing downtime and optimizing data operations through data observability. PhonePe's adoption of Acceldata led to a 65% reduction in the cost of managing data warehouses, equivalent to five million dollars in savings within the first 18 months.
