Data Science Model Deployments and Cloud Computing on GCP - In-Memory Databases

The video tutorial introduces in-memory databases, which store data in RAM instead of on disk, making data access faster but less permanent. It highlights that data does not persist through sessions and explains that in-memory databases often use key-value pairs rather than collections. An example is provided, and the video concludes with a mention of Redis, an in-memory database to be discussed in a future video.

What are key-value pairs in the context of in-memory databases, and why are they important?

Discuss the limitations of in-memory databases as mentioned in the text.
