Event Store Database
Event Store is a database built for event sourcing, allowing you to store and query events instead of state. It provides a highly scalable and available platform for building event-driven applications.
#What is Event Store?
Event Store is an open-source database designed for building event-sourced systems. It provides a reliable and scalable way to store event streams, which are sequences of records that represent changes to an application’s state over time. Event Store can handle both high write and high read workloads and has built-in support for subscriptions and projections, making it easy to build real-time applications.
#Event Store Key Features
Here are some of the most recognizable features of Event Store:
- Event sourcing: Event Store is designed from the ground up for event sourcing, which allows you to build systems that capture and store all changes to your application state as a sequence of events.
- Reliability and scalability: Event Store is built to handle high write and high read workloads, with support for distributed deployments and clustering.
- Subscription and projection support: Event Store provides built-in support for subscriptions, which allow you to receive real-time updates whenever a new event is stored, and projections, which allow you to transform your event streams into new streams or views of your data.
- Multi-platform support: Event Store is cross-platform and can be run on Windows, Linux, and macOS.
- Developer-friendly API: Event Store provides a simple and intuitive API for working with event streams and has SDKs available for multiple programming languages.
- Open-source: Event Store is open-source software and is available under the Apache 2.0 license.
#Event Store Use-Cases
Here are some use cases for Event Store:
- Event-driven architectures: Event Store is ideal for building event-driven architectures, where events are used to communicate between different services or components of a system.
- Real-time analytics: Event Store can be used to store and analyze event streams in real-time, providing insights into your application’s behavior and performance.
- IoT data processing: Event Store can be used to store and process large volumes of IoT data, providing a reliable and scalable way to capture and analyze sensor data.
- Financial applications: Event Store can be used to store financial transaction data and provide an auditable trail of all changes to the data.
- Gaming: Event Store can be used to store player interactions and game events, allowing for real-time analytics and replay of game sessions.
- E-commerce: Event Store can be used to store customer interactions and orders, providing insights into customer behavior and allowing for real-time order processing.
