EP #2: Valkey, Vector, Redis, and the History of Databases - The Open Source Observability Podcast

In this episode we learn how Valkey, the lightning-speed open source key-value datastore, can help improve your observability toolstack. Dive in to learn what differentiates a NoSQL data store from a relational database, more about data structures such as HyperLogLog and Bloom Filter, and all about the history of how data is stored.

Roberto Luna Rojas is a Sr. Open Source Developer Advocate at Valkey. He has nearly 25+ years experience in data modeling, software engineering, and architecture development – from creating 100+ FOSS-based web solutions to contributing as a Sr. Solutions Architect to GenAI and Databases at AWS. He is an expert in the fields of strategic database transformations and AI/ML, with strong career roots and a personal belief in open source.
