Redis is an open source, key-value data structure store. With fast performance and simple onboarding, it can be used as a database, cache, and message broker for businesses across many industries. Redis offers fast handling for in-memory, schema-less database transactions, the ability to ingest and analyze very large datasets, and data caching for high-performance applications.
Monitor your connections to make sure you aren't serving too many at once.
