RedisGears 2.0 introduces a new feature called triggered functions, which allows developers to react to Redis keyspace notifications and execute business logic within the database. The new feature is built on top of the V8 JavaScript engine, providing high-performance execution and low latency. Triggered functions can be used to update inventory levels in e-commerce applications or normalize data from multiple feeder applications. The initial milestone release focuses on functions executed on database triggers, but its usefulness extends beyond that, as most advanced data structures in Redis Stack also publish their events. To deploy a function, developers provide a single JavaScript file, and the JavaScript community has excellent deployment tools available.
