Uber understood that digital superiority required the capture of all their transactional data, not just a sampling. They stood up a file-based datalake alongside their analytical database. Uber chose Presto for the flexibility it provides with compute separated from data storage.
A data hub contains data at multiple levels of granularity and is often not integrated. It differs from a datalake by offering data that is pre-validated and standardized, allowing for simpler consumption by users. Data hubs and datalakes can coexist in an organization, complementing each other.
OnlineAnalyticalProcessing (OLAP) is crucial in modern data-driven apps, acting as an abstraction layer connecting raw data to users for efficient analysis. It organizes data into user-friendly structures, aligning with shared business definitions, ensuring users can analyze data with ease despite changes.
Onlineanalyticalprocessing (OLAP) database systems and artificial intelligence (AI) complement each other and can help enhance data analysis and decision-making when used in tandem. IBM watsonx.data is the next generation OLAP system that can help you make the most of your data.
Like Pinot, StarTree addresses the need for a low-latency, high-concurrency, real-time onlineanalyticalprocessing (OLAP) solution. In addition, StarTree offers a managed experience for real-time and batch Pinot workloads, offering enhanced security, automated data ingestion, tiered storage, and off-heap upserts.
