Best Key-Value Databases for Netdata

Redis Labs is the home of Redis. Redis Enterprise is the best Redis version. Redis Enterprise is more than a cache. Redis Enterprise can be free in the cloud with NoSQL and data caching using the fastest in-memory database. Redis can be scaled, enterprise-grade resilience, massive scaling, ease of administration, and operational simplicity. Redis in the Cloud is a favorite of DevOps. Developers have access to enhanced data structures and a variety modules. This allows them to innovate faster and has a faster time-to-market. CIOs love the security and expert support of Redis, which provides 99.999% uptime. Use relational databases for active-active, geodistribution, conflict distribution, reads/writes in multiple regions to the same data set. Redis Enterprise offers flexible deployment options. Redis Labs is the home of Redis. Redis JSON, Redis Java, Python Redis, Redis on Kubernetes & Redis gui best practices.

Couchbase, unlike other NoSQL database, provides a multicloud to edge enterprise-class database that offers robust capabilities for business-critical apps on a highly available and scalable platform. Couchbase is a distributed cloud native database that runs on any cloud. It can be managed by the customer or fully managed. Couchbase is built using open standards and combines the best of NoSQL and SQL with the power and familiarity that mainframes and relational databases provide. Couchbase Server is an open-source, multipurpose distributed database. It combines the best of relational databases, such as SQL, ACID transactions, and JSON, with a foundation which is fast and scalable. It is used in many industries for things such as user profiles, dynamic catalogs, GenAI applications, vector search, caching at high speed, and more.

Berkeley DB is a set of embedded key-value databases libraries that provide high-performance data management services for applications.

It can be thought of as a temporary memory for your applications. memcached allows for you to take memory from areas of your system that have more than you need, and make it available to areas that have less. This is the classic deployment strategy. However, you'll see that it's not only wasteful because the cache size is only a fraction of what your web farm actually has, but also because it takes a lot of effort to maintain consistency across all nodes. You can see that all servers are looking into the exact same virtual memory pool with memcached. You will also notice that as your application demands increase, so does the amount of data that must be accessed. These two aspects of your system should be scaled together in a deployment strategy.

etcd is a strong consistent distributed key-value store. It provides a reliable way for data to be stored that can be accessed by a distributed system, or cluster of machines. It can gracefully handle leader elections during network partitions, and can tolerate machine failure even in the leader node. As in a standard filesystem, data can be stored in hierarchically-organized directories. Pay attention to specific keys and directories for changes, and react to any changes in values.
