What NoSQL databases have you worked with?

In my practice, I have worked with several NoSQL databases, including:

• MongoDB — a document-oriented database used for storing dynamic data with a flexible schema.
• Redis — a key-value store used for caching and session management.
• Cassandra — a columnar database used for processing large volumes of data with high availability.

For example, in one Java project, I integrated MongoDB using Spring Data MongoDB for convenient working with documents and repositories.
