To be useful for real-time, databases must handle growing exceptionally high data volumes and query loads without sacrificing performance, by supporting horizontal scaling through sharding, partitioning, or other means. Scalability: Real-time applications generate massive amounts of data.For real-time applications, databases must support OLAP workloads to efficiently and quickly extract insights from data as it is generated or updated. Data warehousing and OLAP workloads: Data warehousing and OLAP (Online Analytical Processing) workloads involve complex analytical processing, aggregation, and reporting on large volumes of data, typically for the purpose of understanding patterns, trends, and correlations in business data.In particular, a database should have the following characteristics if it is to be useful for processing real-time data: When you choose a database for real-time applications, you’ll need to consider several important factors. Inventory management: Real-time databases can handle merchandise inventory and transactions in real-time to maintain a live, intelligent snapshot of actual product inventory.Ĭhoosing the right database for real-time applications.Social media and messaging applications: Real-time databases can efficiently manage real-time interactions between users, such as messaging, likes, shares, and comments, providing an engaging user experience.IoT and sensor data: Real-time databases are well-suited for handling high-velocity data streams from IoT devices and sensors, providing real-time analysis and insights into device performance, environmental conditions, and other metrics.Monitoring and alerting: Real-time databases can quickly process and analyze incoming data, allowing systems to monitor and generate alerts for anomalies, threshold breaches, or other critical events in real time.Fraud detection and prevention: Real-time databases can analyze incoming transactions or user activities in real time, helping to identify and prevent fraudulent activity before it causes significant damage.Location-based services: Real-time databases can handle real-time location data from GPS devices, enabling applications to provide real-time navigation, tracking, or location-based recommendations.Sports betting: Real-time databases can process real-time sporting events and bettor behavior to offer the safest and most compelling betting experiences.Gaming: Real-time databases can manage player data, game state, and interactions in online multiplayer games, ensuring a responsive and engaging gaming experience.Personalization and recommendation engines: Real-time databases can process user interactions and behavior in real time, enabling systems to offer personalized content or recommendations during active sessions.Web analytics: Real-time databases are perfect for analyzing web traffic and clickstreams in real-time.Real-time analytics: Real-time databases underpin real-time analytics, allowing businesses to track key performance indicators, identify trends, and make data-driven decisions faster. ![]() For example, you should choose a real-time database if you’re building any of the following use cases: Real-time databases are the go-to choice for applications that require rapid data processing, analysis, and decision-making based on the most recent data generated. What are some use cases for a real-time database? It is optimized for low-latency query performance, high-throughput data ingestion, compute-efficient processing, and handling rapidly changing data. A real-time database handles data storage, processing, and analysis in real-time. They are built to deliver up-to-date and accurate information, enabling both people and applications to make timely decisions based on the latest data. ![]() ![]() Real-time databases are optimized for low-latency query performance, high-throughput data ingestion, compute-efficient processing, and handling rapidly changing data. What is a real-time database?Ī real-time database is a database designed to handle data storage, processing, and analysis in real-time, typically reacting to and processing events or data streams as they occur. In this blog post, I’ll discuss the use cases for real-time databases, and the pros and cons of using several databases - including MongoDB, PostgreSQL, Tinybird, ClickHouse, Snowflake, Pinot, and Druid - for real-time workloads. To be effective for real-time applications, databases must possess exceptionally high performance, scalability, and versatility in handling complex analytical queries. ![]() Real-time data has become an essential component in building user-facing experiences or creating automated decision systems, and developers need a database to match their needs. Selecting the right application database can be a challenge for developers, especially so when you need a database for building real-time applications.
