2. Voldemort (distributed data store) - Wikipedia

   en.wikipedia.org/wiki/Voldemort_(distributed...

   Voldemort does not try to satisfy arbitrary relations and the ACID properties, but rather is a big, distributed, persistent hash table. [2] A 2012 study comparing systems for storing application performance management data reported that Voldemort, Apache Cassandra, and HBase all offered linear scalability in most cases, with Voldemort having the lowest latency and Cassandra having the highest ...

3. Document-oriented database - Wikipedia

   en.wikipedia.org/wiki/Document-oriented_database

   Document stores use the metadata in the document to classify the content, allowing them, for instance, to understand that one series of digits is a phone number, and another is a postal code. This allows them to search on those types of data, for instance, all phone numbers containing 555, which would ignore the zip code 55555.

6. Apache Cassandra - Wikipedia

   en.wikipedia.org/wiki/Apache_Cassandra

   Apache Cassandra is a free and open-source database management system designed to handle large volumes of data across multiple commodity servers. The system prioritizes availability and scalability over consistency , making it particularly suited for systems with high write throughput requirements due to its LSM tree indexing storage layer.

7. NoSQL - Wikipedia

   en.wikipedia.org/wiki/NoSQL

   Different NoSQL databases, such as DynamoDB, MongoDB, Cassandra, Couchbase, HBase, and Redis, exhibit varying behaviors when querying non-indexed fields. Many perform full-table or collection scans for such queries, applying filtering operations after retrieving data.

8. Dynamo (storage system) - Wikipedia

   en.wikipedia.org/wiki/Dynamo_(storage_system)

   Dynamo is a set of techniques that together can form a highly available key-value structured storage system [1] or a distributed data store. [1] It has properties of both databases and distributed hash tables (DHTs).

9. ScyllaDB - Wikipedia

   en.wikipedia.org/wiki/ScyllaDB

   It supports the same protocols as Cassandra and the same file formats (SSTable), but is a completely rewritten implementation, using the C++20 language replacing Cassandra's Java, and the Seastar [1] asynchronous programming library replacing classic Linux programming techniques such as threads, shared memory and mapped files.
